Product Description

The MCOCXO oven controlled oscillator with CMOS output features fast warm up, taking just 30 seconds to reach ±0.1ppm @25°C.

With a choice of packages, including robust DIL 14 package and two types of surface mount package to choose from, this OCXO is versatile enough to be useful within a wide range of applications. Low power consumption of just 50mA maximum (at 25°C) adds to its versatility, as does good shock resistance of up to 5,000G and vibration resistance of up to 20G 10.0-2,000Hz range.

The MCOXCO is available with supply voltage 12.0V at frequencies from 10.0kHz ~ 54.0MHz.
