Output Skew of CY22394

Question: What is the skew we should expect from two different outputs generated by the same PLL ?

 

Answer:

The only way to guarantee 180 degrees phase offset is to use the CY22394 P+ and P- outputs. The only time this phase offset is guaranteed is if you have a divide by 1, which the CY22394 has on the P+ and P- outputs. This will limit your output frequency to 100-400MHz. The P+ and P- clock outputs will swing from 0-3.3V.
