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. 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.
