[time-nuts] Thunderbolt OCXO

[GandalfG8 at aol.com]

I'm not sure if this has been asked before but don't recall seeing it, does  
anybody have a general specification please for the crystal oscillator used in 
 the Thunderbolt?
 
I'm interested in the later one, badged Trimble, rather than the  earlier 
Piezo version, as I've recently bought one of the  small modules from Ebay that 
contains one of these oscillators, plus some  control circuitry to drive the 
EFC pin, and would like to know what to expect of  it as a stand alone unit.
 
regards
