To get to CMOS levels, you usually add a simple inverter, with an capacitor in front and a 1M resistor across the inverter (from input to output). > Actually want to achieve less than around 78ps jitter at 125MHz.

If you feed it with the noisy HC53 output, you will degrade your GPS receivers performance severely. At the minimum, you should use a normal XO for the GPS modul. You can of corse use a HC53 as the reference for your logger if its jitter is ok for you. And for comparison, for a XO you usually talk about jitter in the order of 100fs to 1ps (10kHz-20MHz) Attila Kinali -- Reading can seriously damage your ignorance. -- unknown _______________________________________________ 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.
