Self-calibrating oscillators set new standards

A new range of self-calibrating oven-controlled crystal oscillators can outperform traditional Rubidium oscillators in many aspects.

A new range of self-calibrating oven-controlled crystal oscillators (OCXOs) can outperform traditional Rubidium oscillators in many aspects.

The CFPO-SC1 self-calibrating OCXO series is designed for Stratum 2 applications and provides a free-run frequency accuracy of within +/-16ppb over lifetime, with no external reference such as GPS.

This development from C-MAC MicroTechnology will optimise applications that require the highest precision offered by oven controlled crystal oscillators.

C-MAC MicroTechnology's self-calibrating OCXO will compensate for aging effects that normally require recalibration of the oscillator after it has been installed in the customer's system.

The CFPO-SC1 provides excellent frequency stability over all ambient conditions at a low cost, combined with high reliability and steady-state power consumption of less than 3.0W.

The standard six-pin metal CFPO-SC1 package is a hermetically sealed component, measuring 67.0 x 60.0 x 40.0 mm.

Standard output frequencies include 4.096, 5.0, 8.192, 10.0 and 10.24MHz.

These devices provide a viable alternative to the traditional Rubidium oscillators being used as Stratum 2 references and in other applications.

Compared with Rubidium oscillators the CFPO-SC1 provides higher reliability, enhanced short term and phase noise performance and lower power consumption.

The smaller package and lower cost complement these key advantages.
