Preliminary PLL601-26 Audio Clock Generator FEATURES DESCRIPTION The PLL601-26 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 output, it provides two selectable audio frequencies (12.288MHz, and 24.576MHz), making the chip ideal for handheld, STB and MPEG Video applications. Additional system frequencies can also be supported by cascading the PLL601-26 with PhaseLink’s QTC programmable clock family. XIN/FIN 1 VDD 2 GND 3 27MHz 4 PLL601-26 • Supports the following output frequencies o 12.288MHz audio clock output o 24.576MHz audio clock output o 27MHz reference output • Accepts Crystal or reference clock inputs o Fundamental crystal: 27MHz o Reference input: 27MHz • On-the-fly switching of the two audio frequencies (12.288MHz, and 24.576MHz). • Accepts <1.0V reference signal input voltage • Single 2.5V or 3.3V ± 10% power supply • Available in 8-Pin SOIC GREEN/RoHS compliant Package. PACKAGE PIN CONFIGURATION 8 XOUT 7 FSEL^ 6 DNC 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.
