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.
