hi all,

is there any relation between trace length and phase of a clock signal ? i have to two clock signals of same frequency coming to two devices that should be same in trace length but if there is some difference between the traces then what will be phase difference between the two?
 

The propagation delay of PCB traces is about 5 to 7 ns/m, depending on the geometrie and substrate permitivity. You can calculate the phase shift from this value.
