One difficulty is in finding a Block Diagram with sufficient information

to determine which chip does what.


Does one exist ??


Thank you,


Richard S.

The thunderbolt uses the output of the OCXO for driving internal clocks,
so likely the OCXO output is OK, but a buffer between the OCXO output and
the connector is bad.
