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
Low power consumption
Low aging
CMOS compatible
Double hermetically sealed package
Full military testing available
3.3 Volt operation available
Optional Tri-State
Low harmonic noise
