AD9554 eval board in "freerun" mode

Hey there,

I am bringing up a setup with the AD9554 eval board using a referenceA with 125MHz and system clock of 25MHz but the GUI states my reference is not valid and the PLL is in freerun (see below). I did verify the Reference (single-ended) with Vp-p=1.3v Vmax=680mV and Vmin=630mV

the status below shows that RefA is not valid

My questions are:

1. Is the frequency I configured (125MHz) a valid config?

2. Are the voltage level defined above valid?

3. If the frequency/voltage level all valid then what could be the issue that the refA is invalid and the PLL is in "freerun"?

Please let me know.
