It would be interesting if fractional resolution of the DDS
would be developed using the PHASE interface.
As PHASE ripples, a carry needs to be sent into

Thanks for the assembly listing. Someone else on time-nuts had done quite
the job of reverse engineering the schematics and other information. Seems
like the two of you could collaborate. Sorry do not recall the name.
Welcome to time-nuts.

Hi
There's quite a bit less in the PIC code than I would have expected. If that's
everything that's there, the PIC does very little heavy lifting. Nice job on
the dis-assembly.
Many of the 10 MHz out FE Rb's are actually the 1 pps version that has been
converted to 10 MHz after the fact. The

Hi Herbert,
Nice work ! A few comments that may help you in your quest. There are two
primary methodologies used in the FEI-5680A Rubidium.
It appears, from your picture, what you have is the older style that is analog
for control of the Rubidium frequency control loop. A VERY GOOD THING !
Hi,
Probably Elio will jump in and tell us more on this, but I must advice
that the unit where he did his forensic examination was a FE-5680A of
the 10 MHz fixed frequency output variety (not accounting for the small
adjustment margin)and also has a fixed 1 PPS. This unit doesn't have
