AUDIO CLOCK SELECTION DESCRIPTION
The ABMX0122 is a low cost integrated XO IC with power down feature, designed to work with a fundamental 27MHz crystal to provide the most common audio clocks (8.192, 11.2896, 12.288, 16.9344, 16.384, 18.432, 22.5792, and 24.576MHz) required by sampling rates of 32kHz, 44.1kHz, 48kHz, 64kHz and 96kHz (256, 384 and 512 oversampling ratios). The wide range of audio frequencies makes it ideal for STB and MPEG Video applications.
