DESCRIPTION
The DQXO-3 oscillator has very high accuracy, stability
and low current. The design consists of a CMOS-
compatible hybrid circuit, packaged in a hermetically
sealed standard TO-39 metal package. Permanent,
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 DQXO-3 vary with
frequency. The characteristics of the 400Hz model are
presented in this data sheet.
