Hi Jeff: Another way is using a PIC micro controller, see: http://www.prc68.com/I/PRC68COM.shtml#TVB http://www.leapsecond.com/tools/PPSDIV.ASM Have Fun, Brooke Clarke http://www.PRC68.com http://www.precisionclock.com http://www.prc68.com/I/WebCam2.shtml 24/7 Sky-Weather-Astronomy Cam jshank

Re: [time-nuts] 1Mhz to 1 PPS

I would like to convert a 1 MHz sine wave to a 1 pps TTL. I'm assuming you aren't too concerned about jitter. There are two issues. The first is converting your sine wave into a valid logic level. The second is dividing by a million. If your sine wave has a reasonable amplitude, I'd just
