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 di fferent 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 superi or startup
performance.
