Extended Temperature/COTS
5X7 mm Surface Mount
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.
Features
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
•
•
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
