And the problem with 35 feet of coax is?
That it's bout three orders of magnitude too long for a 50 ps
(picosecond) delay?
I'm rather confused by Joe's followup, myself. If he's talking
about cascading gates to get a delay, maybe he really does mean 50 ns
(nanoseconds). And what does "delay cell" mean? Is this delay thing
part of a discrete circuit, or part of an IC? That much time delay
corresponds to a little less than half an inch, not a problem for
trace length on a PCB, but a lot inside an IC.
And what is a "5-G clock"? Five gigahertz? I can surely understand
informalities when all parties have already been introduced to a
circuit/problem/situation, but please, the first time you post
something, spell things out.
I checked, 50 picoseconds is indeed 1/4 of a clock period of a 5
gigahertz signal, but I had to calculate that to be sure. You'll get a
lot more help, and a lot faster, if you don't make the readers of your
post guess at the basic units you're using.
