Description

The model EX-380, low profile 4 Pin DIP Evacuated Miniature, Oven Controlled Crystal Oscillator (EMXO) available in frequencies from 10 MHz to 80 MHz.

The EX-380 provides exceptionally low aging rates and tight 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"). At 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 -40ºC to +85ºC. Wider temperature ranges are available, i.e. -55ºC to +85ºC. This is achieved by the application of new resonator design concepts and technological breakthroughs. This EMXO series 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 5 Vdc, all with an HCMOS output. A surface mount version of this oscillator is available (EX-385). Sinewave output is available in the surface mount version.
