AD9625-2.5EBZ Rev B1 - Optional Oscillator not working

Hi,

Since I do not have a signal generator capable of producing a 2.5GHz clock, I'm trying to use the on board optional oscillator but I don't seem to be getting a clock output.  Y601 is populated on my board, Y602 is absent.

R602 has been populated

C601 has been removed

C608 has been populated

C607 has been populated

P601 is configured to provide 2.5V to the VC pin (set up the same as FMCADC2 schematic)

Is there something I'm missing?

Thank you.
