LQXO-4 OSCILLATOR 32 kHz to 200 kHz* Low Power Crystal Oscillator ™ DESCRIPTION The LQXO-4 oscillator design consists of a CMOScompatible hybrid circuit, packaged in a standard TO-39 metal package. Permanent, precision tuning of the oscillator 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 LQXO-4 vary with frequency. The characteristics of the 32.768 kHz model are presented in this data sheet. *Consult factory for other frequencies.
