Hello all,
I recently picked up a SA.22c for use in a project and it came with an
interface board that I can't seem to identify; I was hoping you nice
folks might be able to help.
The SA.22c is part of an assembly with the interface board and a metal
plate/heatsink. There is a small cable (approximately 6 inches)
attached to a 10 pin connector on the board. The interface board,
based on the drawings and connector descriptions, does not appear to
be the SA.22c developers board. If I had to guess, this was likely
taken from some other device and wasn't used as a standalone
reference. Ideally I'd lack to track down the specs and connector
pinouts for this board in hopes that I could reuse it and not have to
make a new interface/harness for the SA.22c.
Any help or information you can provide would be greatly appreciated.
More information (part numbers, etc.) below:
The SA.22c itself is labeled with a Symmetricom part number,
SA22C-0029F02E0003, and there is an additional label marked with
"15961-501 REV. E" but this label doesn't carry any manufacturer (I
don't believe it to be a Symmetricom P/N but I could be wrong). The
board is marked with a printed part number of "?6219-15892-001 REV D"
(I can't make out the first digit, maybe a "6"?) and has a sticker
with "15893-501 REV D1". The board has what appears to be a single
SMB connector (J3), a 10 pin connector (J1) (the attached cable uses
six of those pins), a 4 pin connector (J2), and what appear to be a
couple of voltage regulators (U6 and U1) (my guess is so it could use
a single power supply). The 10 pin connector on the board is arranged
in two rows of five, the attached cable terminates with a single row
eight pin connector, six of those pins are connected.
