I have USRP Rev. 4.5 and already Burned one CLK Input of my Distribution Chip with FA-SY1. FA-SY1 has CMOS Output (~3.3V) and the Distribution Chip only copes with 2V max.

So I ordered FA-SY2 LVDS Version with 0,7V Output, but it doesnt work neither. Only Original 64MHz Oscillator works for me.

Does anyone have a Solution how to Connect FA-SY to USRP Rev. 4.5?
