FULL MILITARY DIL XO
QEN 49/55-EH
FULL MILITARY DIL XO
Description
These high performance DIL clock oscillators are designed for high
vibration and extended temperature range up to -55° C to +125° C.
For the same military temperature ranges, our QEN49/55-EH uses
ACMOS active circuit technology with a high performance crystal
resonator mounted on 3 points. It allows an upper frequency of 60 MHz,
as opposed to the classic HCMOS types, which are limited to much
lower frequencies.
Frequency range
14 MHz to 160 MHz
Applications
Test equipment
Military airborne
Space applications
