DESCRIPTION
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.
FEATURES
Double hermetically sealed package Full military testing available
3.3 Volt operation available
