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.
