Radiation tolerant TCXO ideal for high-shock and vibration environments

Euroquartz has released a new range of radiation tolerant TCXO from Greenray Industries Inc. that provide outstanding performance in high shock and vibration environments.

Housed in a rugged, radiation tolerant, stainless steel and nickel-plated package, the new T1276 TCXOs provide frequencies between 2.5MHz and 120MHz over a wide temperature range from -55C to +125C. Ultra-low acceleration sensitivity is lower than 0.07ppb/g, making these oscillators excellent for many applications, incorporating high-orbit transponders, low-orbit nano/microsatellites, RF telemetry systems, multiband terminals and upconverters.

The 24-pin DIP package measures 20.3mm x 12.7mm x 8.9mm and supplies protection from total ionising doses up to 200krad (Si). Further specifications include SEL and SET free to 100MeV cm²/mg, selection of 3.3VDC and 5VDC power supply needs and CMOS or sinewave output.

Frequency stability ranges from ±0.3ppm over 0C to 50C to ±7ppm over the whole operating temperature range. Ageing is ±1ppm in the first year and ±3ppm over ten years. Typical phase noise performance varies from -90dBc/Hz at 10Hz frequency offset to -160dBc/Hz at 1MHz frequency offset.

The new range complements the existing T1254 product line and can be supplied with MIL-PRF-55310 Level B or S screening.
