LXOM OSCILLATOR 10 kHz to 2.1 MHz* ™ Low Power Crystal Oscillator DESCRIPTION The LXOM oscillator has the highest accuracy, stability and lowest current of all STATEK oscillators. The design consists of a CMOS-compatible hybrid circuit, packaged in a hermetically-sealed, half-size 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 LXOM vary with frequency. The characteristics of the 32.768 kHz model are presented in this data sheet. 2k 2T-3 *Consult factory for other frequencies.
