LXO

LXO OSCILLATOR 10 kHz to 2.1 MHz ™ Low Power Crystal Oscillator DESCRIPTION The LXO oscillator has the highest accuracy and stability of all STATEK oscillators. The design consists of a CMOScompatible hybrid circuit, packaged in a hermetically-sealed metal DIP. Permanent, precision tuning of the oscillator is accomplished by laser trimming the crystal after it has been hermetically sealed in a ceramic package and connected to the oscillator circuit. This method of fine tuning allows for very tight calibration tolerance and eliminates the need for a trimming capacitor, a major source of long-term frequency drift. The specifications and characteristics of the LXO vary with frequency. The characteristics of the 32.768 kHz model are presented in this data sheet. z MH .0 0-2 LX PACKAGE DIMENSIONS FEATURES Low power consumption Low aging CMOS compatible Double hermetically sealed package Full military testing available 5V operation standard 2.5V to 15V operation also available E F G H J A I PIN NO.1 D PIN NO.7 B APPLICATIONS C Industrial, Computer & Communications General purpose clock oscillator Data Logger Remote sensor Liquid level sensing Medical test and diagnostics Military Portable field communication Military high speed modem Flight recorder PIN NO.14 PIN NO.8 DIM A B C D E F G H I J inches 0.810 MAX. 0.510 MAX. _ 0.300 + 0.005 _ 0.600 + 0.005 mm 20.57 MAX. 12.95 MAX. _ 7.62 + 0.13 _ 15.24 + 0.13 0.430 TYP. 0.240 MAX. 0.040 TYP. 0.150 MIN. 0.018 0.002 0.070 TYP. + _ 10.92 TYP. 6.10 MAX. 1.02 TYP. 3.81 MIN. _ 0.46 + 0.05 1.78 TYP. * Position of bumps for reference only 10110 - Rev D S YS TEM C ERT I F I C AT N IO STATEK CORPORATION 512 N.
