LMX2595EVM: LMX2595 PHASE SYNC

Part Number: LMX2595EVM
Other Parts Discussed in Thread: LMX2595

Hi there,

I am experiencing an issue with PHASE SYNC on the LMX2595.

I attempted to synchronize multiple LMX2595 devices using the same configuration as shown below.

  1. Would this configuration fall under Category 1?
  2. Checking the outputs on an oscilloscope, they appear to be synchronized. However, when measuring S21 phase using a VNA with an external module, the phase changes each time I perform the measurement. Could you please tell me if there is any other problem?

 

Thanks,

G Son
