Selectable Audio Clocks supporting: F s of 32kHz, 44.1kHz, 48kHz, 64kHz and 96kHz 8.192MHz, 11.2896MHz, 12.288MHz, and 24.576MHz audio frequencies On-the-fly switching of the audio frequency. 2.5V and 3.3V (±10%) Operating Voltage. Available in 8-pin SOP GREEN/RoHS compliant packaging 8 XOUT 7 S0^ 6 S1^ 5 ACLK 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. 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.
