LX01-1.0MHz - Statek Corporation

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.
