Evacuated Miniature Crystal Oscillator
EX-400
Description
The EX-400 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-400 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.
