Oven Controlled Crystal Oscillators

This new oven controlled crystal oscillator (OCXO) product series is designed for high volume production and is 100% tested for thermal stability, aging, output level and spectral purity, phase noise, short-term stability, warm-up and continuous power, reference voltage and electrical tuning range. A low active component count helps ensure high reliability.

The 270 series double oven OCXO drops into a standard European CO-08 footprint and is available with an output frequency between 4.8 to 90 MHz. Utilizing a full-size TO-8 quartz-resonator, the oscillator performs to the stability required for Stratum II and IIIe, GPS, and TDMA PCS applications. Specifications include thermal stability performance of 2.0E-10 to 5.0E-09 over a –30°C to +70°C ambient temperature range, steady-state power consumption of 1.7W from a nominal +12 VDC supply at 25°C ambient, warm-up power of 5.5 W typical, and frequency stability of 5E-09 after approximately 10 minutes. Typical RF output is +9 dBm ± dB sinewave (into a 50W load) with <-30 dBc harmonics and –80 dBc suprious levels. Short-term stability at 1 sec is 2E-12.
