hello,i designed a pcb with adf4360-6,I have a problem with adf4360-6, i have try several days ,but it still unlock
The ref_clock is 9.8304MHz, and the RFout that I want is 9.8304*126 = 1238.6304MHz, the N out and Rout is right,the loop filter is
desighed from simpll sortware, but it still unlock.
i found the cp pin is pulse on the datasheet, i attched the cp pin output when i disconnect the loopfilter after it, is the cp pin output correct? what is the correct cp pin output? where is the prolemmaybe is?
