SQXO2SM OSCILLATOR
10 kHz to 2 MHz*
Surface Mount Low Power Crystal Oscillator
™
DESCRIPTION
The SQXO2SM oscillator consists of a CMOS-compatible
hybrid circuit, hermetically sealed in a standard 24-pin
ceramic leadless chip carrier. Precision tuning of the
oscillator 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 SQXO2SM vary with frequency. The
characteristics of the 32.768 kHz model are presented in
this data sheet.
