Si5338 Phase step INC/DEC accuracy on
Clock Generator, Buffer, Crystal Oscillator Forum
I am currently using the Phase INC/DEC function with the Si5338.
1) The datasheet says that the accuracy of phase steps is "20ps" MAX.
2) And for example on this post, we have an example of how to set up a 20ps phase step size
-> So my question is: why is the quoted accuracy of 20 ps while it seems to perform much better? what is the limitation (temperature effects, ageing, ... ? )? Is there a Silabs alternative which would achieve 3ps?
