CY22381 Response to 180 Degrees Input Phase Change!
When the reference clocks phase changes, there will be a noticeable change to the output frequency as it adjusts lock to the new clock. The output will also experience high cycle-to-cycle jitter for a short time. The lock time, however, is much less than the power-on lock time.
Look at the attached document that shows how the CY22381 responds when the reference clock has a 180 degree phase change.
