I have an HP Z3816A GPS timing receiver. It has 4 of its output connectors at 19.6608 MHz. I gather this was for cellular telephone service.
Just curious... 19.6608 MHz seems like an unusual frequency. Is there some logical reason why that frequency was chosen for this application? I see this is 12C0000 in hex (or 300 * 65536). I guess this may be part of the reason. Would be pretty easy to divide down to 0.01 second intervals. I've been thinking of trying to hack the circuit board to convert the drive for these 4 outputs to also be at 10 MHz. I wonder if anyone else has already done this and could save me a lot of circuit tracing. -Rex _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
