Euroquartz has introduced a Statek's crystal oscillator that is suitable for high temperature, high shock applications. Offering frequency output from 460kHz to 50MHz, the HGXOHT oscillator operates between -55 and +225°C. The oscillator is suitable for applications including downhole instrumentation, rotary shaft sensors, underground boring tools and avionics. It comprises a hermetically sealed high-shock crystal and a CMOS-compatible IC housed in a 5x7.5mm, SMT, ceramic package. It features good stability over temperature , an optional enable and disable, and is transistor-transistor logic compatible. It has a 3.3 or 5V supply voltage, calibration tolerance of ±50ppm, 15pF output load, 5ms start-up time, 10ns rise and fall time, and shock survival up to 100,000g. It features maximum process temperature of 260°C for 20s.
