Si53312 can't drive DIOT EEM Adapter clock lines #32

It seems that Si53312 has too little drive strength to be able to drive balun on DIOT EEM Adapter. There is no signal on MMCX output.

AC coupling helps, output signal has 310 mVpp (50 Ohm termination).

Currently Si is configured to have 1V8 power supply and LVDS outputs. LVPECL is available only on 2V5 or 3V3 power supply.
