Over the past year many people have asked for special features in those cute little 8-pin PDIP PIC divider chips that I play with and use in my lab.
I've updated the web page: http://leapsecond.com/pic/picdiv.htm There are now close to 20 different versions. Here's a partial list: PD03 -- "4-pin" 10^3 frequency divider (10 MHz to 10 kHz) PD04 -- "4-pin" 10^4 frequency divider (10 MHz to 1 kHz) PD05 -- "4-pin" 10^5 frequency divider (10 MHz to 100 Hz) PD06 -- "4-pin" 10^6 frequency divider (10 MHz to 10 Hz) PD07 -- "4-pin" 10^7 frequency divider (10 MHz to 1 Hz) PD08 -- "4-pin" 5x10^6 frequency divider (5 MHz to 1 Hz) PD09 -- "4-pin" 10 MHz to 1PPS frequency divider (20 us pulse) PD10 -- "4-pin" 10 MHz to 1PPS frequency divider (10 ms pulse) PD11 -- 10 MHz to 1PPS frequency divider (3 pulse widths), with sync PD12 -- 5 MHz to 1PPS frequency divider (3 pulse widths), with sync PD13 -- 10 MHz to three frequencies divider (1-10-100 Hz), with sync PD14 -- 5 MHz to three frequencies divider (1-10-100 Hz), with sync PD15 -- 10 MHz to three frequencies divider (1-1k-10k Hz), with sync PD16 -- 5/10 MHz to four frequencies divider (1-10-100-1000 Hz) PD17 -- 1/2.5/5/10 MHz to 1PPS frequency divider (100 ms), with sync PD18 -- 1/2.5/5/10 MHz to 1PPS frequency divider (10 ms), with sync PD26 -- 10 MHz to 1PPS frequency divider, with sync and microstep Note these are all compatible with the TAPR T2-mini board (which comes with a PD17). /tvb http://leapsecond.com/pic/ _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
