ADF4350 programming

Question asked by Daz on Mar 24, 2011

I am having trouble getting the ADF4350 to program correctly.  My routine is bit banging the data into the device and I have tried clocking in on the rising edge and the falling edge, but still......I cannot get the ADF4350 to lock to the frequency I program into it.

 

Does anybody have any ideas?

 

I have attached a screen capture of the clock data and load enable lines to see if this would shed any light on why I cannot get the device to program.
