[time-nuts] ANFSCD - Synchronizing time in home video recorders

Hi Tom,

I'm interested in that divider. Actually, insterested in knowing how it 
works, not in the .HEX file.

Breseham's algorith works but has inherent jitter and I've found no other 
solutions for situations like that.

I'd live to know how it is done.

Thank you,
Roberto EB4EQA

Yes, I have a PIC divider that takes 5 or 10 MHz input and
outputs a 32.768 kHz square wave with minimal jitter and
no long-term phase offset. Contact me off-line if interested.
