It might be easier to go the other away around... take a GPS receiver with a programmable output frequency and set it to produce 32768 KHz. The Venus timing receivers can produce accurate output frequencies (but with a fair amount of jitter, which would be irrelevant to a clock display).
I think that the Venus timing receivers use a factional N divisor scheme that can produce exactly 32768 Hz from the 120 MHz processor clock. Other receivers with programmable outputs may or may not be able to. Nick Sayer has a Venus timing module for around $40 The $6 NavSpark Mini receivers also use a Venus chip with a programmable output, but I don't know if their frequency generator is as fancy as the timing receiver. I'd check mine, but my frequency counters are all tied up for quite a while. _______________________________________________ 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.
