DESCRIPTION
The PLL601-27B is a low cost integrated XO IC
designed to work with a fundamental 27MHz crystal
or clock input. In addition to a 27MHz clock reference,
it provides the most common audio clocks (8.192,
11.2896, 12.288, and 24.576MHz) required by
sampling rates of 32kHz, 44.1kHz, 48kHz, 64kHz and
96kHz, making the chip ideal for STB and MPEG
Video applications.
