LXOM-AT OSCILLATOR 500 kHz to 120 MHz TM Low Power Crystal Oscillator DESCRIPTION The LXOM-AT consists of a TTL and CMOS-compatible hybrid circuit and a miniature quartz crystal packaged in a hermetically-sealed metal DIP. Permanent, precision tuning and a hermetically sealed AT quartz crystal allows for very tight calibration tolerance and eliminates the need for a tuning capacitor, a major source of long-term frequency drift. 2k 2T-3 FEATURES Low aging CMOS and TTL compatible Double hermetically sealed package Full military testing available 3 Volt operation also available Optional Tri-State or Output Enable C F APPLICATIONS PACKAGE DIMENSIONS D E H PIN NO.1 G PIN NO.4 Industrial, Computer & Communications General purpose clock oscillator Military Flight recorder A B OUTPUT WAVE FORM PIN NO.8 PIN NO.5 VDD VOH 90%* 10%* DIM A B C INCHES 0.505 MAX. _ 0.300 + 0.005 mm 12.83 MAX. _ 7.62 + 0.13 VOL 0 0.430 TYP. 0.225 MAX. 0.025 MAX. 0.150 MIN. _ 0.018 + 0.002 10.92 TYP. 5.72 MAX. 0.64 TYP. 3.81 MIN. _ 0.46 + 0.05 * Of VDD tr tf D E F G PACKAGING H 0.063 TYP. 1.60 TYP.

TRI-STATE Enable: When pin 1 is low (0), the oscillator stops oscillation. Tri-state: When pin 1 is low, the oscillator is running. However, the output buffer amplifier stops functioning and output is in high impedance (Z) state.
