Differential Propagation Delay
IMR , 06-21-2016, 09:22 PM
Hi, I'm trying to use the following part to recover and remove jittter from a HDMI clock signal. Looking at figure 4 of the datasheet and the AC electrical characteristics table it can be seen that there is a propagation delay of 1.4ns. How do I adjust the lengths of the other data pairs to compensate the delay on the clock pair?

Hi @IMR. I am not sure what you are trying to do, but adding a buffer may not remove jitter. Jitter may be caused by the generator.

In a differential routing what does gap actually mean? is it center to center distance or edge to edge?

Inner edge to inner edge

Is it accepted among different design tools? I am using Mentor Graphics Hyperlynx for stack up design.

Gap / clearance is the space between two tracks. It is same understanding / definition in all software (at least in all the software I used including Cadence Allegro, PADS, ...).
