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.
