LXOM-AT OSCILLATOR 500 kHz to 120 MHz 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 PACKAGE DIMENSIONS Double hermetically sealed package Full military testing available 3 Volt operation also available Optional Tri-State or Output Enable D E C F H APPLICATIONS Industrial, Computer & Communications PIN NO.1 G PIN NO.4 General purpose clock oscillator Military A Flight recorder OUTPUT WAVE FORM VDD VOH VOL 0 90%* 10%* * Of VDD tr tf PACKAGING LXOM-AT - Tube Pack (Standard) B PIN NO.8 PIN NO.5 DIM INCHES mm A 0.505 MAX. 12.83 MAX.
