LXO OSCILLATOR
10 kHz to 2.1 MHz
Low Power Crystal Oscillator
™
DESCRIPTION
The LXO oscillator has the highest accuracy and stability 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 LXO vary
with frequency. The characteristics of the 32.768 kHz
model are presented in this data sheet.
