Hi Danny,
I'd want to take a close look at output jitter (phase noise)- you
may be playing with fire if you bypass the voltage regulator and
run the unit off a supply that is not squeaky-clean.

Hi Danny
This is exactly what we do with our standalone ROACHs in the field. I haven't
noticed any problems with the 5005. We don't have any 5007s to try though.

Dear All
We are the proud new owners of some Valon 5007 synthesizer modules, which we
plan to use to clock our ROACHes:

It has a 5V LDO voltage regulator, so they recommend an input voltage of 6V. We
were thinking of just powering these with the ROACH ATX 5V supply and housing
them inside the ROACH chassis; has anyone done this before or have any advice?
Cheers
Danny
