Hi all,

I am working on a design In which I have two clock that needs to be in sync always, however these two clocks are from different source. I want to add a phase shifter or delay line in between one of the clock so I can adjust the phase difference after the manufacture of the PCB.
The frequency of the clocks are 4 GHz. I could not find any phase shifter that can work at this frequency.
Is there any device on any other method through which I can adjust the phase on PCB

Thanks

This is tricky.
Are these frequency sources are synchronized? if they have delay i.e depend on the power on sequence then there is no mean to have delay line.
We need to have some kind of gating.
