LXO-AT

LXO-AT OSCILLATOR 500 kHz to 120 MHz ™ Low Power Crystal Oscillator DESCRIPTION The LXO-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. z MH .0 -70 LX0 FEATURES Low aging CMOS and TTL compatible Double hermetically sealed package Full military testing available 3 Volt model also available Optional Tri-State or Output Enable E F G H J APPLICATIONS PACKAGE DIMENSIONS I Industrial, Computer & Communications General purpose clock oscillator Military Flight recorder Airborne hybrid computers B C PIN NO.1 A D PIN NO.7 PIN NO.14 OUTPUT WAVE FORM PIN NO.8 VDD VOH DIM A INCHES 0.810 MAX. 0.510 MAX. 0.300 0.005 0.600 0.005 0.430 TYP. 0.240 MAX. 0.040 TYP. 0.150 MIN. 0.018 0.002 0.070 TYP. + _ + _ + _ mm 20.57 MAX. 12.95 MAX. _ 7.62 + 0.13 _ 15.24 + 0.13 90%* 10%* B C D E VOL 0 10.92 TYP. 6.10 MAX. 1.02 TYP. 3.81 MIN. _ 0.46 + 0.05 * Of VDD tr tf F G H I J 1.78 TYP. * Position of bumps for reference only 10111 - Rev D STATEK CORPORATION 512 N.
