DESCRIPTION

The PLL601-27 is a low cost integrated XO IC designed to work with a fundamental 27MHz crystal or a 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. PACKAGE PIN CONFIGURATION 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.
