So does the basic idea make sense? More importantly can somebody opine
on if it's possible to use a 1PPS to discipline an OCXO (I've seen
designs to it from a 10KHz signal for sale on eBay)) -
Yes, many devices, both professional and amateur,
use a precise 1PPS signal to discipline Qz, Rb,

I'm curious about the 10 kHz signal. Can you send
me a pointer to it? Usually 1 Hz is good enough and
in practice most GPSDO use an averaging algorithm
that is more akin to 0.01 Hz to 0.001 Hz.

Silabs has some 8051 cored chips that run at 100 MHz with close to 1
instruction/cycle. I use them (not for timing), they really are speedy.
The C8051C123 runs at 100 MHz with 2 built-in DACs (and a bunch of other
goodies, such as 128kB of flash, 8k of RAM, 2 x 8 input ADCs, one 8
bits/500ks/s,
