EX-400
Evacuated Miniature Crystal Oscillator
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.
• 4-Pin Dip
• Uses Doubly Rotated Crystal
• Low Power Consumption: <0.35 watts @ +25°C
• Previous Model Number: EX-380, EX-381, EX-385 series
• Frequency Range: 10 MHz - 80 MHz
• SONET/SDH, DWDM, FDM, ATM, 3G
• Telecom Transmission and Switching Equipment
• Wireless Communication Equipment
• Military Airborne and Mobile systems
