Extended Temperature/COTS
XO, 5.0V
20KHz to 100MHz
Features
Tiny 5 x 7 SMD form factor
Hermetically sealed for rugged environmental
conditions
Extremely wide operating temperature range
accommodates harsh environments
All crystals are processed in-house with tight angle
control to assure best frequency-temperature
characteristics
All units are vacuum baked before sealing at 175°C
for 16 hours to eliminate moisture traces and pre-age
units for superior stability
RoHS Status
Description
Owing to their small size, light weight, and
rugged characteristics, these 5V HCMOS
extended temperature/COTS oscillators fulfill
tasks not previously feasible. They are used in
applications that take advantage of their
extended temperature range and high
performance. Twenty four different models (with
and without tristate) cover -55°C to +200°C
operation and provide frequency selection from
20 KHz to 100 MHz. They combine excellent
long-term reliability, loading characteristics, and
superior startup performance.
