A picosecond is 1000 femtoseconds. When you're spending $100/ea. on parts rated for 60-70 fs jitter, a picosecond starts to look like a long time indeed. > > Does not sound like you are doing the Nuts any service to address > > things that are orders of Magnitude below usefulness. When designing something like this, it's useful to understand where, and why, your efforts fall short of the state of the art. That way you can be sure that the compromises you're making are the right ones. The idea is not to leave any obvious low-hanging fruit for optimization. You want to get the most out of the money you're spending, whether it's $200 or $20,000, right? I do think there's a lot of room between "state of the art" timing performance and conventional TIC-grade performance where corners can be cut and costs can be saved. It's helpful (and more interesting) if you can make those calls rationally, instead of just adopting circuits from papers and hoping for the best. -- john, KE5FX _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
