What kind of clock sources be used for the clock input of the device? Can a synthesizer like ADF4371 be used to drive it? If yes, please advise on the circuit else please suggest the appropriate approach.
Thank you for your help in advance,
At page 11 of the datasheet, there are two different interfacing for clock input of the device, please refer to those figures. The CLK pin should be kept @2V DC and the swing can be +-400mV on top of that. To adjust the clock amplitude, a resistive network like Figure A1 could be used.
