Description

The model EX-380 Series is a low profile DIP or SMD, Evacuated Miniature Oven Controlled Crystal Oscillator (EMXO), available in frequencies from 10 MHz to 80 MHz.

The EX-380 Series provides exceptionally low aging rates and high temperature stabilities in an extremely small package over a wide range of environmental conditions. The through hole unit measures only 20.8mm x 13.2mm x 7.6mm (0.82" x 0.52" x 0.30"), @ 10 MHz provides aging rates of <1x10- 9/day average, <1x10-7 for the first year and <1x10-6 for 10 years with temperature stabilities to ±1x10-7 over -40 to +85. Wider temperature ranges are available from -55 to +85. This is achieved by the application of new resonator design concepts and technological breakthroughs. This series of EMXO's bridges the gap between current large, high precision OCXO's and smaller TCXO'S. The EX-380 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.

Standard supply voltages for the EX-380 series are 3.3 Vdc and 5Vdc, with HCMOS or Sinewave output options. A surface mount version of this oscillator is available (EX-381/5). Sinewave output is only available in the surface mount, EX-381, version.
