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.

TRI-STATE Enable: When pin 1 is low (0), the oscillator stops oscillation. Tri-state: When pin 1 is low, the oscillator is running. However, the output buffer amplifier stops functioning and output is in high impedance (Z) state. Output Levels TTL CMOS VOL 0.4V MAX. 0.5V MAX. VOH 2.4V MIN. 4.5V MIN. Start-up Time 5 msec. MAX.
