DESCRIPTION
The SQXO-2-SM 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 SQXO-2-SM vary with frequency. The
characteristics of the 32.768 kHz model are presented in
this data sheet.
