Hello, I am using the SPI port to control a cdce72010. My goal is to take in the AUX CLK input and use it to drive the dividers directly, leaving the pll off and the FB divider off. My registers are programmed to the values below (read back from the device), but I do not get a clock out of the part at all in this mode. I have successfully configured it for an 800mhz vcxo and a 100mhz primary reference and secondary reference, but the ext clk just doesn't seem to work. Any insight is greatly appreciated.
