LXOAT OSCILLATOR 312 kHz to 120 MHz Low Power Crystal Oscillator DESCRIPTION The LXOAT 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.
