Extended Temperature/COTS

XO, 3.3V

20KHz to 100MHz

Features

Tiny 5X7 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

Tristate feature optional

Equivalent 5V parts are available in series T1254

RoHS Status

Description

Owing to their small size, light weight, and

rugged characteristics, these 3.3V 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 six different models

(with and without tristate) cover -55°C to

+200°C operation and provide frequency

selection from 20KHz to 100MHz. They

combine excellent long-term reliability, loading

characteristics, and superior startup

performance.

Applications

Any electronic circuit requiring 3.3V HCMOS

clocking that is exposed to very high or very low

temperatures such as oil drilling or weather

observation equipment
