27MHz reference output (from 27MHz crystal input or clock input). Selectable Audio Clocks supporting: 48kHz, 64kHz and 11.2896MHz, 12.288MHz, and 24.576MHz audio frequencies On-the-fly switching of the audio frequency. 3.3V Operating Voltage. Available in 8-Pin SOIC.

The is a low cost integrated XO IC designed to work with a fundamental 27MHz crystal or a clock input. In addition a 27MHz clock reference, it provides the most common audio clocks 11.2896, 12.288, and 24.576MHz) required by sampling rates 48kHz, 64kHz and 96kHz, making the chip ideal for STB and MPEG Video applications.

Note: Internal pull-up resistor. The internal pull-up resistor results in a default high value when no pull-down resistor is connected to this pin.
