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.
