CFPO-DO Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Range of Super Single Oven OCXO’s

CFPO-DO Series
ISSUE 1; 19 OCTOBER 2004
Description
■ The CFPO-DO series are a range of Super Single Oven
OCXO’s designed as a compact and smart frequency
source/time keeping reference for all synchronization
systems including global ositioning system (GPS)
based equipment
CFPO-DO series key performances are:-
■ Holdover better than 7µs over 24 hours
■ Frequency stability over operating temperature range
( see table text )
■ Frequency stability versus change of all operating
conditions (pressure, supply, load, etc.)
