design review

[gkasprow]

• [x] the power detector thresholds are free floating: DET_TRH_REV; DET_TRH_FWD; maybe add another MAX DAC
• [x] the JK flip flop RSTn and CLK are shorted together on top entity which don't make much sense to me
• [x] don't we need some manual reset button?
• [x] won't T4 saturate due to slight output current imbalance?
• [x] add LEDs: overtemp, FWD interlock, REV interlock; power good, P12V, P48V
• [x] missing P3V3_CPCIS source
• [x] there are a lot ERC and DRC errors
• [x] add connector labels: EEM, fan
• [x] add power rail LEDs and testpoints; possibly all in same PCB region, look at KASLI-DIOT
• [x] don't we need more vias under exposed copper? It's gonna make RF cages with outer shield/heatsink
• [x] be careful with such pads; we can make panel cutout as we do in other designs
• [x] milling cuts bottom layer
• [x] copper cannot touch board edge - make 0.5mm clearance
• [x] missing proper DIOT ESD strip and resistors - copy it from Kasli-DIOT
• [ ]

won't T4 saturate due to slight output current imbalance?

Core has Isat at least 7A, max current in Id of MRF101 in this application will be lower than 1A.

[gkasprow]

• [x] please add trimpots to adjust bias during board tests

[gkasprow]

• [x] Move the fine-tune input to the front panel, as in other designs like WENZEL_REF
• [x] Make the reset button available from the front panel; use ordinary PB_TYCO_1-1825027-1
• [x] Make sure the RF connectors are positioned as in newest Urukul - we want to re-use plastic distances
• [x] Please add 3D model of the 6HP front panel (from Wenzel for example)
• [x] please add 3D model of heatsink/shield
• [x] when adding series resistor to the ADC input, remember about storage capacitor (10nF or so) to the ground at the ADC input.
• [x] FIN1028 has failsafe feature - with inputs unconnected, it will produce 3.3V at the output holeind DET_RST permanently high. Add P-MOSFET in parallel to PB3 or inverter (like IC29)
• [x] Where the power supply of IC29 is defined (VCC net) ? Add note on the schematic.
• [x] put info about RF transformer ratios on the schematic
• [x] IC33 will oscillate with ceramic caps, use 1..22u tantalum ones or add 100mOhm in series with C104

Changed to LT1117

[shanasz]

• [ ] correct ordered part list
• [x] check debug connectors / testpoints for all test scenarios
• [x] send 3D model changes (wider cave for tune connector and reset button)

[shanasz]

• [x] correct PD placement
