P1P40167

P1P40167 1.8V, 4-PLL Low Power Clock Generator with Spread Spectrum Functional Description The P1P40167 is a high precision frequency synthesizer designed to operate with a 27 MHz fundamental mode crystal. Device has 4 PLL’s with four LVCMOS outputs and a reference clock. The frequencies generated are 22.5792 MHz, 24.576 MHz, 48 MHz and 37 MHz as well as a 27 MHz copy of the reference clock. Device offers flexible spread spectrum options configurable through I2C bus. All output clocks are generated with high precision, zero PPM frequency conversion, thus making it suitable for high−end multimedia and consumer applications. I2C is included to support various system configuration options.
