I am trying to program the ADF4351 and am able to get some output but I'm not able to change the frequency. It is always stuck at 1832MHz no matter what I try.
In terms of debug effort, I can confirm that SPI is working because I can control the MUXOUT and the PWRDWN pin configurations. The current consumption is around 80mA I have looked at the LD pin and I am measuring 0V at the output and when I configure the MUXOUT to output the analog lock or digital lock I also get 0V out. So I think the PLL is not locking. How do I go about confirming that the PLL is getting locked?
