GPS Disciplined Oscillator review and teardown

inside-allAndy Brown did a teardown of a GPS Disciplined Oscillator:

The design did actually surprise me. I was expecting to see an OCXO pulled from something else together with a modern GPS unit and an MCU to co-ordinate the synchronisation all mounted on a custom PCB. What we’ve actually got is an entire Symmetricom GPSDO pulled from some other device and mounted on to a trivial minimal PCB that does nothing more than break out connections to the front panel.

More details at Andys Workshop blog.

Check out the video after the break.

  1. The link “” on the PCB resolves, but has no content, even with scripting enabled. I won’t bother digging further.
