DAC synchronisation in Sayma v2.0

[hartytp]

Proposal for DAC clocking and synchronization in Sayma v2.0:

• users supply the RTM with a reference clock (frequency f_ref) via the front panel (FP) SMA this will be the only supported clocking path (until/unless we adopt some fancy WR-type PLL, which can distribute a high-quality clock to the RTM via DRTIO)
• users supply the AMC with a RTIO clock (frequency f_rtio) either via FP SMA (master/standalone) or via fibre + CDR (satellite)
• in the first instance, the only configuration supported in gateware/firmware (NB this is not a hw limitation) will be f_ref = f_rtio to minimize complexity. In future it won't be too hard to support different configurations, such as f_ref=100MHz f_rtio=125MHz. NB the cost of a really low-noise PLL from Wenzel or similar to generate this clock is small compared with the overall cost of ownership of Sayma
• the reference and rtio clocks must be phase locked together (e.g. by locking to a common reference)
• the RTM reference clock will be buffered with a low-noise buffer (e.g. ADCLK925) and sent to the AMC via the AMC<->RTM connector, as well as an HMC830. This will be useful for future diagnostics. (Unless you don't think this is worth it @sbourdeauducq)
• All clocks and important signals on the AMC + RTM will be accessible via suitable test points, such as UFL connectors!
• a HMC830 on the RTM generates the DAC clock at up to 2.4GHz by multiplying the reference clock (NB for integer-N synthesis, the input-output propagation delay is deterministic)
• the HMC830 output is buffered (again, ADCLK925 or similar) and fed directly to the DACs. There is a constant propagation delay/phase offset (limited only by drift in PLLs and buffers) between the DAC clocks and the reference/rtio clocks. The is no frequency division here, so there is no non-deterministic phase offset
• To synchronize the DACs to the RTIO clock, all that needs to be done is to supply a SYSREF pulse from the AMC FPGA that meets S/H at the DACs (w.r.t. the DAC clock, which can run at up to 2.4 GHz)
• In principle, the SYSREF pulse could be generated directly by the FPGA. However, the S/H window for a 2.4GHz DAC clock is something like 200ps, which will be hard to achieve for a variety of reasons: drifts between the phase of the RTIO and reference clock due to the SI5324 (already something like 100ps); FPGA jitter; SI between the two boards; general VT fluctuations in all components; etc
• As a result, we opt to put a discrete, low jitter FF on the RTM to retime the SYNC pulse produced by the FPGA. This FF is clocked by the RTM reference clock. This ensures that the FPGA is able to generate a low-jitter SYNC pulse with a fixed phase relationship to the RTM reference clock
• since the input timing window for this is close to 8ns, meeting S/H timing is relatively easy (we could nonetheless choose to buffer these signals and route a copy to the RTM FPGA for diagnostics if @sbourdeauducq thinks it's worth it?)
• in principle, we could fix the time delay between the FF output and the DAC SYSREF pin by trace length to ensure that S/H timings are always met in HW. However, given how narrow the timing window is, I'd be inclined to add a phase trim to this. The easiest way of achieving this is with a very simple digital delay line placed after the FF, such as http://www.onsemi.com/PowerSolutions/parametrics.do?id=586

Edit: we could consider adding solder jumpers to allow the FF + phase shifter to be bypassed in Sayma v2.0 if anyone wants to have a go at driving SYSREF directly from the FPGA.

Comments?

[hartytp]

Other notes on this:

1. We will no longer have a clock for the JESD204B ADCs. This is fixable (e.g. add a second HMC830) but, given that there don't actually seem to be any users of the JESD ADCs, I'd prefer to get rid of them. (If it's a choice between simple, reliable DAC synchronisation and JESD ADCs, I take the synchronization scheme ever time). In any case, users can always add fast ADCs to the AMC FMC port
2. Need to buy a phase shifter eval board and measure the propagation delay temp co to check that there won't be issues there (highly unlikely, but needs testing)
3. NB the idea of the above is that we keep the bits of phase synchronisation that already work well in ARTIQ (programming the HMC830 and setting the analog phase of the SYSREF to meet S/H at the DAC), but replace the HMC704x with a simpler solution that isn't bogged down with buggy features that we don't want

If everyone (@sbourdeauducq @gkasprow @jbqubit and anyone else who still cares) is happy with this proposal, we can discuss whether it's possible to retrofit this synchronisation setup onto Sayma v1.0 for testing

[hartytp]

Let's go for NB6L295M as the phase shifter unless anyone has a better idea. NB this has two channels, so we can trim the DAC sysref phases independently. Not sure if that's actually necessary, but might as well give ourselves the option

[hartytp]

@gkasprow any preference/suggestion for which FF to use?

[hartytp]

Unless anyone else has a better suggestion, let's use MC100EP51 (I really like ON for this kind of discrete logic). The SOIC version should be fine for dead-bugging/prototyping.

[dhslichter]

All clocks and important signals on the AMC + RTM will be accessible via suitable test points, such as UFL connectors!

:+1: I think getting rid of the JESD204B ADCs is the right thing to do. @gkasprow has preferences in terms of ripping out traces vs. simply DNP, and I defer to his preference on that subject.

Let's go for NB6L295M as the phase shifter let's use MC100EP51

Both of these parts look suitable to me.

One other question - how do we verify we are meeting S/H on the DACs for the SYSREF, i.e. is there a clean mechanism to calibrate the phase shifter/delay line that can be done without the need for accessing test points on the board?

Edit: we could consider adding solder jumpers to allow the FF + phase shifter to be bypassed in Sayma v2.0 if anyone wants to have a go at driving SYSREF directly from the FPGA.

Given the simplicity of the FF + phase shifter solution, and the known problems with trying to keep drifts from ruining your timing window if driving SYSREF directly over the RTM connector from the FPGA, I can't imagine a use case where one would prefer to drive directly from the FPGA rather than through FF + phase shifter. I think the phase shifter is definitely needed/desired, it's simple SPI control, we validate that it works sensibly in a dead bug setup...

[hartytp]

Well, note that if we follow this proposal there will no longer be an ADC clock/SYSREF generation. So, getting the ADCs to function requires more than just populating them, they need a new clock synth/divider/etc.

One other question - how do we verify we are meeting S/H on the DACs for the SYSREF, i.e. is there a clean mechanism to calibrate the phase shifter/delay line that can be done without the need for accessing test points on the board?

Yes, the DAC has sysref validation built in. We currently use this in ARTIQ and it works fine (all that needs to be done is a fw switch to move from using the analog phase shifters in the HMC7043 to the SPI delay line, but that's trivial).

[hartytp]

Here is a pretty shoddy illustration of what I have in mind, in case it helps...

[hartytp]

Plans for testing this on the hw:

• I've ordered a phase shifter eval board as well as a couple of those FFs in the SOIC package
• I'll dead bug a FF onto the phase shifter eval board
• I'll connect the FF data line to the AMC FPGA using one of the FP SMAs
• i'll supply the clock for the FF from my main 150MHz clock synth using a power splitter
• I'll program the HMC7043 as a normal buffer (fundamental mode + no analog phase shift) so it's not taking any part in the synchronisation and has completely deterministic latency
• I'll disconnect the HMC7043 SYSREF signals by DNPing the AC coupling caps
• I'll solder coax pig tails onto the cap pads and use that to hook the phase shifter to the DAC sysref inputs
• I'll connect the phase shifter SPI bus to the RTM somewhere. Probably using the clock mezzanine header (unless @gkasprow can suggest some more easily accessible pins on the AMC/RTM)
• I'll do a really quick check of the phase stability of the phase shifter using a hot air gun and scope (remember SYSREF only needs to be stable to <100ps or so, so the stability isn't crucial)
• I'll see if I can get the SYSREF working with this setup

How does that all sound?

[hartytp]

@gkasprow please can you send me my AMC + RTM back to do these tests with? Thanks!

[sbourdeauducq]

the RTM reference clock will be buffered with a low-noise buffer (e.g. ADCLK925) and sent to the AMC via the AMC<->RTM connector, as well as an HMC830. This will be useful for future diagnostics. (Unless you don't think this is worth it @sbourdeauducq)

The FPGA needs a clock for the JESD transceivers and there are some constraints as you noticed. We might need a 2X (250MHz) clock. Someone should check the exact transceiver clocking resources.

since the input timing window for this is close to 8ns, meeting S/H timing is relatively easy

Someone has to check datasheets / experiment / validate this but we can perhaps make the FPGA scan a delay on a short pulse (less than one period of the flip-flop clock) while checking if the DAC receives any SYSREF. Then the timing window at the FF can be derived.

As a result, we opt to put a discrete, low jitter FF on the RTM to retime the SYNC pulse produced by the FPGA. This FF is clocked by the RTM reference clock. This ensures that the FPGA is able to generate a low-jitter SYNC pulse with a fixed phase relationship to the RTM reference clock

The FF could also absorb the timing variation due to place-and-route, which is very high even when using the global clock network with those annoying Ultrascale chips.

[hartytp]

The FPGA needs a clock for the JESD transceivers and there are some constraints as you noticed. We might need a 2X (250MHz) clock.

Yes, I was in the middle of writing exactly that when you posted. Can we use use the Si5324 to provide the transceiver ref clock?

[hartytp]

Someone has to check datasheets / experiment / validate this but we can perhaps make the FPGA scan a delay on a short pulse (less than one period of the flip-flop clock) while checking if the DAC receives any SYSREF. Then the timing window at the FF can be derived.

What exactly are you worried about? That FF has well-specified timing windows, with S/H of 100ps. For a 125MHz clock, that's a pretty huge window to hit, even when SI etc are taken into account (whatever its failings might be, the SI on Sayma has proved to be excellent).

The FF could also absorb the timing variation due to place-and-route, which is very high even when using the global clock network with those annoying Ultrascale chips.

True, that's nice. So long as those variations are small compared to the 8ns timing window of the FF these can be absorbed.

[sbourdeauducq]

For a 125MHz clock, that's a pretty huge window to hit,

Things always go wrong on Sayma! Without precautions, by default it will hit that 100ps window, guaranteed!

Can we use use the Si5324 to provide the transciever ref clock?

No, the Si5324 provides the DRTIO transceiver clock already.

But that 2X clock, if we actually need it (someone has to dig into the Xilinx docs), does not need any phase synchronization and can be produced with a basic divider on the 2.4Ghz clock.

[hartytp]

Things always go wrong on Sayma! Without precautions, by default it will hit that 100ps window, guaranteed!

Yes, in the long run, we'll need some kind of eye scan on that to determine the correct phase for the FPGA SYNC. Still, I'd rather implement that than keep fighting the HMC7043.

But that 2X clock, if we actually need it (someone has to dig into the Xilinx docs), does not need any phase synchronization and can be produced with a basic divider on the 2.4Ghz clock.

AFAICT from skimming over UG567, we do need this: the CPLL output needs to be at a minimum frequency of linerate/2, which is 5GHz for 10GSPS line rate required to run at 1GSPS. The max feedback divider is 5*5=25, so the minimum input clock required to run at full data rate is 200MHz. Might be worth someone checking this with Xilinx?

FWIW, I've tried building Sayma without sawg for 10GBPs line rate, 125MHz RTIO, 250MHz ref clk, and it builds without any warnings. So, that configuration appears supported, although I don't have any HW to test on.

As you say, let's add a divider here, it's a nice cheap easy solution. Feel free to suggest your preferred part (@gkasprow) that can go up to 2.4GHz, but NB6N239S might be a good choice. Just needs some pin straps and has two outputs with independent dividers.

No, the Si5324 provides the DRTIO transceiver clock already.

Does it not have enough outputs to do both?

[hartytp]

Side note: this scheme is conceptually a bit ugly since we're rebuilding about 30% of the HMC7044's functionality for about 300% of the cost (but, still nothing compared with the total cost of Sayma) using discrete logic. But, it has the big advantage that we now have simple building blocks that can be probed and debugged independently rather than a poorly documented black box with known bugs. Ugly, but practical.

[hartytp]

No, the Si5324 provides the DRTIO transceiver clock already. Does it not have enough outputs to do both?

If not, is it worth using one of the chips in that family that has more outputs? Might be simpler and cheaper than using a separate divider. Anyway, let's do this whichever way you prefer.

[dhslichter]

But that 2X clock, if we actually need it (someone has to dig into the Xilinx docs), does not need any phase synchronization and can be produced with a basic divider on the 2.4Ghz clock.

Or a 2x doubler of the RTIO clock, if that's simpler...

[hartytp]

Or a 2x doubler of the RTIO clock, if that's simpler...

Lots of ways of skinning a cat. That would also work...

Since the GTH PLLs are not very flexible and have a few non-obvious constraints, it's nice to have a programmable reference frequency. So, we probably want a switchable divider/multiplier here.

FWIW, my feeling is that the easiest way of doing this would probably be to replaced the Si5324 with a model with more outputs, such as a Si5366, which is essentially the same cost as the Si5324. Anyway, let's leave this decision to @sbourdeauducq

[hartytp]

@sbourdeauducq why are we AC coupling the AD9154 sysref inputs? I guess it's not a problem so long as we are careful to gate the DAC's sensitivity to them, but it seems a bit odd not to DC couple this.

Edit: with the synchronization system proposed here, we probably want to DC couple the DAC SYSREF inputs. If desired, we can connect the phase shifter output enable pin to the RTM FPGA and high-Z those outputs once synchronization is complete and the DAC is no longer sensitive to SYSREF edges.

[sbourdeauducq]

No good reason. Better DC-couple if possible (@gkasprow) as AC-coupling would interfere with the FF timing scan scheme I proposed.

[sbourdeauducq]

It's not an ugly scheme at all. Probably it has less total transistors than the HMC7044 :) If chip vendors didn't suck, they would just put that circuit into one small low-cost device instead of inventing monstrosities.

[sbourdeauducq]

FWIW, my feeling is that the easiest way of doing this would probably be to replaced the Si5324 with a model with more outputs, such as a Si5366, which is essentially the same cost as the Si5324.

It's not the same, e.g. the loop bandwidth is different and there are other features. Maybe the simplest is to keep the 5324 (which has two outputs with independent dividers) and either keep the fanout buffer or modify siphaser so everything runs from the GT clock input and the fabric input is no longer required. I do not have time to look into this right now. When removing the fabric input, whoever does the test needs to check the impact on timing accuracy, as the GT input to the fabric path may have skew variations.

That being said, clocking all transceivers from the AMC side sounds OK and would save RTM connector pins. Though we may want to keep those RTM transceiver clocks (use the other GT input pins on the FPGA) for other applications or in case there are unforeseen issues.

[hartytp]

Yes, the HMC7044 is pretty close to being a perfect solution for us. But, in the end, it crams in way too much functionality that can't be properly bypassed and which interacts with the features we need in odd ways.

Another thing I like about this sync scheme is that it keeps the number of components in the DAC clock path to the absolute minimum. This is key to getting good phase noise/drift performance.

ACK. Well, let's not worry about this just yet. Let me demonstrate the sync scheme works (ping @gkasprow about posting my Sayma back) first then we can come back to these finer details when we have more time.

[hartytp]

@gkasprow do you have a test board that breaks the IO from the high density connectors used on the AFEs out to something more accessible like 100mil header? If so, can you post me one when you send my Sayma back, please? This would be very useful for connecting the delay line eval board up to Sayma for synchronisation testing...

[gkasprow]

Maybe you'd prefer to use clock mezzanine and its control lines? I have a board with all IO lines routed to I2C extender.

[hartytp]

Thanks @gkasprow. However, I'm not sure that will help very much, as there is no convenient way of getting the IO off that test mezzanine. Ideally, I was hoping for a robust way of routing the IO off the board and into a wiring harness. e.g. a board with the high-density connector hooked up to 100mil header would be perfect. If that doesn't exist, I'll just use a PCB mount connector + some glue

[hartytp]

@gkasprow Are all the vias directly under the HMC7043 grounded?

[gkasprow]

Yes. I verified it with multimeter to be 100% sure.

[hartytp]

Thanks.

[hartytp]

With apologies for the low quality photos, some results...

Firstly, my test setup.

https://drive.google.com/open?id=1zYejNeNXbiX0iktJA8cpZx2M4cFJEwVh

Red squares on strip board are a 3V3 LDO and the FF. There is a phase shifter eval board attached with hot glue. All stripboard and gaffer tape are strictyly microwave grade.

The SMAs on the strip board are inputs for the 150MHz clock (split from my reference with a MCL power splitter) and the TTL SYSREF generated by the FPGA. Matching to ECL done with resistor networks (hard to make out). The two coax lines soldered onto the board are the retimed SYSREF and SYSREF_N outputs from the FF. Measured jitter is <60ps pk-pk.

One flip flop drives both phase inputs on the dual phase shifter chip (the stub this creates is small and doesn't cause SI issues).

The phase shifter eval board is controlled via SPI using a breakout adapter I made for the clock mezzanine IO. https://drive.google.com/open?id=1m6oCQK4kDcNLN2X3SWA6-x36L8c-srxP

The SYSREF from the FPGA is output to SMA 0 on the AMC and then looped into the FF using coax (SMA)

[hartytp]

Here is an eye measurement.

• green is the 150MHz reference (another MCL power splitter)
• yellow is the phase-shifted sysref
• blue is the 2.4GHz DAC clock
• scope is on infinite persist with 10 min of DAQ time

As you can see, jitter isn't really an issue even for the max DAC clock

https://drive.google.com/open?id=1NO_GqqXIX0TIgscn0_wgG_AXuOOhbsDa

[hartytp]

Oops, wrong eye photo, that one didn't have the clock on persist. Should have been this one (still consistent with scope jitter)

[hartytp]

Video showing the phase shifter working. Steppin one delay line in 1 LSB (11ps) increments at a rate of 1LSB/S.

https://drive.google.com/open?id=1EJ4rNzYQF8aQdXBBAEc5-Vf_J85HfQrR

[hartytp]

I'll let everything cool down for a while now and then take an eye measurement with persist as thigns warm up. That will give us an idea of how much of an issue stability is likely to be. NB I don't have a fan on the delay line or FF so they will get relatively hot compared to use in a uTCA crate, so this should be a reasonable "worst-case" indication...

[hartytp]

@gkasprow @sbourdeauducq other than the warmup drift measurement, is there anything else you want to see before we agree to adopt this synchronisation scheme. Based on the data, it seems that if these DACs can be synchrnoised then this scheme will do it.

I will try to attach them to the DAC and demonstrate synchronisation directly, but the rework is going to be tough and I'm running out of time.

[hartytp]

FWIW, heating the phase shifter and FF with an air gun that was hot enough to start melting my glue, I saw about 300ps pk-pk change in the phase at the scope. That suggests that once the board has warmed up for a few minutes the stability should be fine.

[dhslichter]

@hartytp this is excellent! Thanks for doing these tests, this seems like a nice solution for Sayma 2.0.

[hartytp]

Yes, it all seems to work exactly how we want. Ideally, I'd like to see synchronized RF at the DAC's output on a scope, but the rework on Sayma required to do that is going to be a complete PITA, so I'm putting it off for now...

[hartytp]

Comment about temperature coefficients: the delay line data sheet specifies a maximum PVT variation as 10.7ns-7.2ns=3.5ns. Assuming that's all due to temperature and that the variation is linear -- both probably quite pessimistic assumptions -- the temp co would be 25ps/K. The max frequency DAC clock is 2.4GHz, so 416ps period. For DC signals, S+H is 108+64ps. So, we need the phase to be good to about 200ps for this to work. That means that the phase shifter chip needs to be stable to about 8K, which should not be an issue at all.

Note, however, that we may need the DACs and phase shifters to warm up a little before synchronisation...

[hartytp]

Delay stability + jitter when for ~20min, starting from cold and with no fans on the delay line or FF:

about 50ps pk-pk so absolutely fine!

[hartytp]

First go with Sayma RTM

• cut the trace connecting the HMC7043 to the AC coupling capacitors

• soldered coax onto both capacitor pads for mechanical stability

• AC couple the outputs of the phase shiftor and connect to the RTM via coax

• 50Ohm AC terminate the coax near the HMC7043 so there is a roughly 2inch stub after the termination. That's pretty nasty for a 2.4GHz signal! But, I don't have the tools to start soldering 0201 resistors across the DAC pads.

• An eye scan on Sayma using the digital delay line

• taps are 11ps, 1/2.4GHz = 38taps, setup and hold are something like 10 taps each:

NB

• true indicates that a realignment has occurred (i.e. a sync error), so patches of false are where we want to work
• patches of true indicate a S/H violation. Assuming ~200ps S + H we expect the width of these patches to be <= 15 taps in the absence of any additional jitter and perfect rise times on our signal

So, we see some decent ~15tap=160ps wide working zones. That indicates that this should be (just about) workable.

In particular, based on this, my guess is that when we improve the SI a bit this will work really well

[hartytp]

NB this is using the DAC's one shot mode, so the statistics are one measurement per point. Probably better to use one-shot then monitor mode in future to get better statistics

[hartytp]

Repeat of that measurement

One thing to reiterate about this new synchronisation scheme: it only takes care of synchronising the SYSREF signal w.r.t. the local RTIO clock; it does not align the DAC clock itself. Instead, we rely on the HMC830 PLL having deterministic input (reference) to output (DAC clock) latency, which it does so long as it's used in fundamental mode (no output divider). That means it's limited to DAC clocks between 1.5GHz and 2.4GHz.

That't generally fine for us because we will want to use interpolation anyway. I've tested the 4x interpolation on Sayma with 600MHz clock rate and, pleasingly, it seems to work fine without any issues (just change one register value).

If it is an issue then I think we can get around it by routing a copy of the DAC clock to the RTM FPGA. We then recycle the SYSREF sampler logic that @sbourdeauducq has already implemented to measure the DAC clock phase w.r.t. the RTIO phase and reset the HMC830 (e.g. change the output divider between two values) until it has the correct phase. This should be relatively straightforward to do (we already do something similar for the DRTIO transceivers), but someone has to implement it.

Anyway, I don't think any of this is a real issue for ARTIQ. @gkasprow can you comment on whether this is okay for non-ARTIQ users of Sayma.

@gkasprow what do you think about this:

• I'm doing eye scans for Sayma RTM DAC SYSREF.
• Taps are 11ps
• for each tap I take 11 points. '.' indicates that the DAC measured the same SYSREF phase as the previous attempt. 'x' means that it measured a different SYSREF phase and switched to the new phase (so xx usually means that it switched the phase twice, ending up at the original phase)
• specified DAC S/H timings are about 10taps

Typical eye scan for 600MHz DAC clock (x1 interpolation, 150 taps per clock cycle):

[hartytp]

• my sysref is 9.375MHz in all cases, generated by the FPGA. It's retimed to the 150MHz reference clock that feeds the HMC830 and its phase is controlled by an external delay line. It's then fed to the DAC using external coax

[hartytp]

So, @gkasprow the things I don't understand and want your input on are:

1. Why does it look great for 600MHz and so bad for higher DAC clock frequencies? If there is a SI issue shouldn't we see that on the 600MHz scan, but just with wider margins? The only explanation I can think of is that there is increased ground/etc noise at higher clock frequencies which makes the SI worse
2. There seems to be some periodic structure in the 1.2GHz sample. Note that each point for the same delay is a repeat measurement, so I would expect the 'x' and '.' to be random on each row.

[hartytp]

All I can think of is that: I will have a go at doing a synchronization test at 600MHz (I will use a scope to post-select data points where the HMC830 divider starts with the correct phase since that's something we can't control without additional HW changes). Once I've done that, I'll send my whole test setup to Greg to see if he can improve the SI

[hartytp]

Okay, I just don't understand that. Repeating the 1.2GHz measurement, but taking more points. The sequence here is:

• set delay line phase
• wait 100us
• as the dac to check if the sysref phase has settled repeatedly
