[time-nuts] HP-10811AB-OCXO interface questions

[Manfred Bartz]

Hi all,

I bought 2 x 10811 OCXOs for a 10MHz GPSDO project I am working on.
The OCXOs came with an interface board HP 05328-20027, see attached
pictures.

Questions:
1. Is it worth keeping the interface board?
    a. If yes, does anyone have the schematic and the data on the ICs?
    b. What is that TO220 device?  and
    c. why is it mounted on a standoff on the back of the PCB?
2. Any advice/caution on matching the OCXO output impedance?
3. Any recommendation for a (>= 4-ch) distribution amplifier?
4. Any advice on a low jitter comparator for further digital processing,
e.g. for a 1pps signal?

Thanks and 73
