LSM OSCILLATOR
30 kHz to 200 kHz
TM
Low Power Surface Mount Crystal Oscillator
DESCRIPTION
actual size
The LSM oscillator has the highest accuracy, stability and
lowest current of all STATEK surface mount oscillators.
The design consists of a hermetically-sealed CX-4
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.
