CFPO-DO SERIES
ISSUE 6; 27 NOVEMBER 2008 - RoHS 2002/95/EC
Description
Super single Oven Controlled Oscillators (OCXO’s)
manufactured for us by Rakon. Designed as a compact
and smart frequency source/time keeping reference for all
synchronization systems including global positioning system
(GPS) based equipment. Key performance characteristics
are:
Holdover better than 7ms over 24 hours
Frequency stability over operating temperature range (
see table text )
Frequency stability versus change of all operating
conditions (pressure, supply, load, etc)
