DQXO3SM OSCILLATOR
1 Hz to 10 kHz*
(R)
Surface Mount Low Frequency Crystal Oscillator
DESCRIPTION
The DQXO3SM 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 tolerances and eliminates the need for a trimming capacitor, a major source of long-term frequency drift. The specifications and characteristics of the DXQ03SM vary with frequency. The characteristics of the 400 Hz model are presented in this data sheet.
