LXO1 OSCILLATOR 10 kHz to 2.1 MHz Low Power Crystal Oscillator DESCRIPTION The LXO1 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 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 LXO1 vary with frequency. The characteristics of the 32.768 kHz model are presented in this data sheet.
