If you want to go Tom's picDIV route, and are lazy like me, this is one
of several boards available.
You'll get several copies of the bard board for under $10. Few minutes
stuffing it, and you'll have a working device...
> Hi Lee,
> It's not likely you can directly multiply 1PPS up to 32 kHz, but it's easy to divide 10 MHz down to 32 kHz.
> See http://leapsecond.com/pic/src/pd30.asm for a $1 PIC example.
> A stand-alone 10 MHz OCXO or the simplest possible GPSDO would work for your digital clock project. Chris and Nick and many others have shared low-cost Arduino-class examples to the list over the years. Another example is the MCU-less James Miller design which uses a PLL at 10 kHz.
> Contact me off-list some day when want a Trimble Thunderbolt; they are still available.
