Wow, thanks for all the information.
Thanks Bruce Griffiths, the LTC6957 is expensive but looks very good
for sine to square wave conversion.
Thanks Lester Veenstra for the details on some of the devices on the
interface PCA and the link to the TLV3501 signal conditioning module.
Thanks Bob kb8t
Missing body of my previous message (I hope):
As others have said, there are a number of versions of the 5328A
oscillator support board. Yours looks like it is from a MIL version of
the 5328A with the 10811 OCXO. Attached is the most-likely schematic,
which is from the manual for the 5328AH9

a 5328 counter. There are two ver

Look in the HP5328A counter manual for the circuit - that's what this
came from, indicated by the board marking. Seems like an awful lot of
extra circuitry to support the OCXO. The only thing I can think of
offhand is it may be a PLL circuit to allow locking to an external
reference. You'll pro

For sine to square wave conversion use LTC6957 (select variant to suit
following logic).
