ADF4111 Initialization

I'm hoping that someone can confirm my initialization procedure for the ADF4111.  I've attached two different methods.  One is by using the CE pin and the other is via the Initialization latch.  I can't get it to lock and there absolutely 0V on the CP pin.  It most certainly could be our loop filter but I'd like to know if I have the firmware correct before I go down that path too far.  Even if the loop filter was way off shouldn't there be at least some voltage on CP?

 

Thanks!

Jonathan
