What is the supported reference crystal input waveform for ADF4159？？
Is there any recommended 100MHz crystal type？
REFIN can be a square wave, a pure sine wave or a clipped sine wave, but must meet the datasheet requirements in terms of REFIN Sensitivity, REFIN Frequency/Slew rate and nominal threshold of VDD/2.
We use the 100MHz crystal clock oscillator CWX113-100.M from Connor Winfield on our evaluation board.
OK，I got it！Thank you very much～
