High-reliability 14-PIN DIL / MIL specification oscillators

05-07-2016 | Euroquartz | Passives

Designed for use in applications that require high reliability, two new ranges of high-specification crystal oscillators have been introduced by Euroquartz. Housed in industry-standard 14-pin DIL (dual-in-line) packages, the 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, the 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 25C and frequency tolerance of ±100 to ±50ppm over the full military temperature range from -55C to +125C (±100 to ±30ppm over industrial temperature range from -40C to +85C).

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 demanding 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, says the company.
