Dear ADI engineer, hello!
I have a little question about PLL. I want to use a mixed signal as a reference signal for the PLL. Specifically, a 180MHz signal is mixed with a 30MHz signal, and the 210MHz signal obtained is input to the phase-locked loop chip HMC440 to participate in phase detection, so how much spurious signal of 180MHz needs to be suppressed in order not to interfere with phase detection, I need this data to design Bandpass filter, can you give me some suggestions?
Best wishes！
