Hi:
As shown in the figure below, the LMX2595 PLL simulation does not match the measurement results.
The LMX2595 output is used as the sampling clock of the DAC. The DAC outputs a 100MHz sine waveform.
When testing its phase noise, it is found that there is a peak at an offset of 200KHz.
However, according to the PLL software, there is no such peak.
Thanks!
