ETC2 CFPO-DO-451S12A50N Range of super single oven ocxoâ Datasheet

CFPO-DO Series
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.)
