Euroquartz Launches New Mil-Spec High Reliability Crystal Oscillators

Frequency control specialist, Euroquartz has launched two new ranges of military specification crystal oscillators designed for use in applications that require high reliability. Housed in industry standard 14-pin DIL (dual-in-line) packages, the new EQXO-1000BMK and EQXO-3000BMK clock oscillators incorporate a custom-designed quartz crystal and a CMOS/TTL compatible hybrid circuit on a ceramic substrate.

Manufactured using the latest advances in production technology, these oscillators are capable of achieving tight frequency calibration tolerance and high stability over a wide temperature range. Frequency range is from 200kHz to 200MHz with calibration tolerance of ±30ppm at 25°C and frequency tolerance of ±100 to ±50ppm over the full military temperature range from -55 to +125°C (±100 to ±30ppm over industrial temperature range from -40 to +85°C).

The high reliability ceramic substrate is packaged in a hermetically-sealed DIL metal package with four pins (EQXO-1000BMK) or 14 pins (EQXO-3000BMK) for extra mechanical security. Additional specifications include 5000g shock survivability, 20g vibration survivability, double-sealed design, low EMI emission and standard 5.0V DC supply voltage (other voltages on request). Start-up time is 5ms maximum with rise/fall time of 6ns maximum and minimum duty cycle of 40%, 60% maximum. Standard output is CMOS, 50pF with other outputs available to special order.

Ideal for aerospace, defence and other applications where high-reliability clock oscillators are required, the new EQXO-1000BMK and EQXO3000BMK crystal oscillators can be screened to MIL-O-55310F, class B if required.
