Frequency control specialist, Euroquartz, has introduced Statek’s latest crystal oscillator designed for high temperature, high shock applications.
Offering frequency output from 460kHz to 50MHz, the new HGXOHT is capable of operating up to 225°C and can survive extreme shocks up to 100,000g. Applications include downhole instrumentation, rotary shaft sensors, underground boring tools and avionics.
The design comprises a hermetically-sealed high-shock crystal and a CMOS-compatible IC housed in a five by 7.5mm surface-mount ceramic package. Additional features are said to include excellent stability over temperature, fast start-up, optional enable/disable and low EMI emission.
Specifications include 3.3 or 5.0V supply voltage, standard calibration tolerance of ±50ppm, output load of 15pF, start-up time of five milliseconds maximum, rise/fall time of 10ns maximum, duty cycle of 40 per cent minimum/60 per cent maximum, vibration survival of 20g and operating temperature range from -55 to 225°C.
