The Model 680 series is a set of small sized,
light weight, and rugged HCMOS extended
temperature/COTS crystal clock oscillators with
5.0, 3.3, 2.5, or 1.8 supply voltage for operations
under stringent environments. They are used in
applications that take advantage of their
extended temperature range and tight
temperature stability. They combine excellent
long-term reliability, loading characteristics, and
superior start-up performance.
