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.
