High reliability military specification oscillator

Euroquartz has launched a new series of military specification clock oscillators for use in aerospace, defence and similar hostile environment applications

Frequency control specialist, Euroquartz has launched a new series of military specification clock oscillators for use in aerospace, defence and similar hostile environment applications.

The new EQXO-2000BM series oscillators are housed in the popular 8 pin dual-in-line (DIL) package and offer frequencies from 30kHz to 70MHz with frequency stability of either +/-100ppm (2100BM types) or +/-50ppm (2050BM models) over the full military temperature range from -55 to +125C EQXO-2000BM devices feature a custom designed, all-ceramic oscillator substrate and ruggedised three-point crystal mounting system within a hermetically sealed metal package ensuring high reliability.

The design specification ensures that these oscillators provide an accurate and reliable source of clock signals regardless of the severity of the environment in which they operate.

For equipment used in space or the upper atmosphere, the EQXO-2000BM series oscillators can be produced in radiation tolerant versions.

Designated EQXO-2000BMH, these parts are designed to withstand ionising radiation enabling the oscillators to resist electrical failures for a total radiation dose of 40krad(SI).

Specifications include calibration tolerance of +/-10 to +/-25ppm at 25C, 5.0V DC +/-10% supply voltage, CMOS output, 50pF/10 TTL loads, ageing of +/-3ppm maximum in first year and output wave symmetry of 45/55%.

Full screening of components in accordance with MIL-O-55310C, Class B is available to special order.
