Description
 
A TCXO ( Temperature Compensated Crystal Oscillator) has extra circuits to compensate for the effects of temperature on the output frequency and provides a very stable reference frequency for improved accuracy and performance of your D/A Converter.

An uncompensated crystal oscillator might have ±30 ppm frequency change over its operating temperature range, but the TCXO will be accurate to within ±1 ppm.

The TCXO uses quartz, a common mineral (silicon dioxide) which is piezoelectric, meaning that if a crystal is mechanically stressed, a voltage will develop across it. Conversely, a voltage impressed across the crystal will mechanically deform it; it will expand or contract. This conversion of mechanical to electrical energy and vice-versa provides a convenient means to build a high quality oscillator.

A small disk or bar of quartz is ground to precise mechanical dimensions, silver electrodes are plated on each side, support wires are attached, and the unit is mounted in a hermetic package.
