A long thread was running on various ways to process a 10MHz (or other) sinewave to reduce measured jitter (presumably limited by slew rate). This note is a quick look at what the 74HC4046 signal input circuit yields; since it was mentioned in 1 post as possibly useful.
Jitter was measured on a DTS-2075 with a 0.18uf blocking cap and a 10:1 resistive divider probe. This provided +/- 250mV into the DTS & an AC coupled, 500 ohm load on the 4046 output. The sinewave source was the 10MHz ref-out from a PM6681, it's the quietest +9dBm signal available to me. _______________________________________________ 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.
