Self-calibrating OCXO to compete against traditional rubidium oscillators

Keywords: Oscillators

C-MAC MicroTechnology, a Solectron company, has added to its extensive range of frequency control products a range of self-calibrating, oven controlled crystal oscillators (OCXO) which in many aspects outperform traditional rubidium oscillators. The CFPO-SC1 self-calibrating OCXO series is designed for "Stratum 2" applications and provides a free-run frequency accuracy of within +1 to 1.6_10−8 over lifetime, without any external reference such as global positioning system (GPS).

This development from C-MAC MicroTechnology will optimize 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 re-calibration of the oscillator after it has been installed in the customer's system.

The CFPO-SC1 provides excellent frequency stability versus all ambient conditions at a low cost, combined with high reliability and power consumption as low as ~3.0 Win steady state. The standard six-pin metal CFPO-SC1 package is a hermetically sealed component, measuring 67.0 × 60.0 × 40.0 mm (L × W × H). Standard output frequencies include, 4.096, 5.0, 8.192, 10.0 and 10.24 MHz.

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