The crucial feature of the 59992A was support for DC-bias, and that seems to have dictated its design. If you have no need for DC-bias, an 8-pin microcontroller with a stable crystal and suitable resistor networks on the outputs will do fine. TI measurements on top of DC-bias was important in development and manufacturing of disk drives: Measurement of jitter of mechanical origin must happen on the analog side of the differential read amplifier, which usually balances a couple of volts up for cost reasons. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
