LSM

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. side view PACKAGE DIMENSIONS 2 FEATURES 3 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 APPLICATIONS 1 4 F TYP.
