[time-nuts] Low cost synchronization

[Joe Landers]

Mike,

If you're interested in LF chip-level products, you
might want to try:

The U4223B looks like the Temic. It was a bit difficult
to get samples from them here in the US, but I've used
both the U4223B and CME8000 with reasonable results.

Some of their product line is now available from Digikey.

On the second, I've only found these leads so far:

These chips appear to be basic receiver circuits using an 
external 60KHz crystal as a filter.
