DQXO3SM OSCILLATOR
1 Hz to 10 kHz*
®
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.
