LSM OSCILLATOR 30 kHz to 400 kHz Low Power Surface Mount Crystal Oscillator DESCRIPTION The LSM oscillator is an ultra-low current quartz crystal oscillator with a typical start-up time of 500ms. The design consists of a STATEK crystal, and a CMOScompatible 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. PACKAGE DIMENSIONS FEATURES 2 3 1 4 Ultra-low power consumption Typical start-up time of 500ms Typical rise and fall times of 25ns Hermetically sealed ceramic package F Optional output enable/disable with Tri-State Full military testing per MIL-PRF-55310 available Designed, manufactured, and tested in the USA 3.3 volt operation available APPLICATIONS Industrial, Computer & Communications General purpose clock oscillator Data logger Remote sensor Real time clock Medical test and diagnostics Military TYPICAL inches mm inches mm A 0.400 10.16 0.405 10.29 B 0.180 4.57 0.185 4.70 C* 0.071 1.80 0.079 2.00 D 0.200 5.08 0.205 5.21 E 0.080 2.03 0.085 2.16 F 0.050 1.27 0.058 1.47 G 0.055 1.40 0.063 1.60 Termination material is Au over Ni (SM1), solder dip (SM3) also available. *SM1 Termination; SM3 = 0.084 in.

The Tversion has a Tri-State output and continues oscillating internally when the output is put into the high Z state. The N-version does not have PIN 1 connected internally and so has no Tri-State/Disable capability. The following table describes the Tri-State/Disable option T. Output Tri-State (Pin 1 High*) Disable (Pin 1 Low) Frequency Output High Z State Internal Osc. Oscillates Oscillates Current Lower than Normal Normal * When PIN 1 is allowed to float, it is held high by an internal pull-up resistor.
