DESCRIPTION
The LSM oscillator has the highest accuracy, stability and
the lowest current of all STATEK surface mount
oscillators. The design consists of a STATEK crystal, and
a CMOS-compatible integrated circuit. The hybrid design
is hermetically-sealed with a kovar lid in a surface mount
ceramic package. Permanent precision tuning of the
oscillator is accomplished by laser trimming the crystal.
FEATURES
