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.
