Got snake bit trying to buy AD633's on ebay, apparently I got rebadged RC4200s instead and one of them blew up the power supply in my test circuit. The guy is arguing about refunding me. Anyway, I am looking at using a XOR gate as a frequency doubler, but can anyone say if this circuit can strip BPSK with the way that it does the frequency multiplication?

Matt I can't say it will strip BPSK. But it will double the input frequency if the RC time constant is half the incoming 1/2 cycle. Also watch out for noise. Depending on the distance to WWVB it can really mess up simple circuits.

Hi The only issue I see is that it looks like it “drops out” at the phase shift point. Past that, it appears to roughly do what you want to do. If the drop out is really there, will convert the PM to AM. Worst case it might glitch at this point and throw off the divider. (which would be a problem).
