Vectron EX-4201-EEJ-758 Evacuated miniature crystal oscillator Datasheet

EX-420
Evacuated Miniature Crystal Oscillator
EX-420
Description
The EX-420 provides exceptionally low aging rates and tight temperature stabilities in an extremely small package over a wide
range of environmental conditions. This EMXO series bridges the gap between current large, high precision OCXO’s and smaller
TCXO’s. The EX-420 Series becomes the most economical choice where there is a need for spectral purity, short and long term
stability, along with small size and dramatically reduced power consumption.
