Can anyone suggest a good reference design for a zero-crossing detector? I am trying to home an ADC sampler trigger to the 1VRMS (50ohm) 10MHz sin from my XL-DC... And now I'm thinking that I should just home the uC clock to it, as well.
Essentially, I believe that I'm looking for an efficient, stable, and accurate sine-to-square converter... and I'll welcome any advice in this area. This may also be used in a 1KHz 5Vpp IRIG-B decoder... I don't feel like rectifying the signal, to be honest. I want to try to keep a smaller BOM, sense the waveform primarily, and crunch numbers inside the uC. -CH Chris Hoffman cq.k...@gmail.com http://ar.ctur.us _______________________________________________ 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.
