LSM OSCILLATOR
700 kHz to 2.1 MHz
Low Power Surface Mount Crystal Oscillator
™
DESCRIPTION
actual size
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.
