Extended Temperature/COTS

XO, 5.0V

20KHz to 100MHz

RoHS Status

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

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



Applications

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.



Dawn-hole PCB applications that require an

HCMOS/TTL 5V clock and that might be

exposed to extremely harsh environmental

conditions.
