| January 2007 rev 0.1 Multi-Output Clock Synthesizer Features * Generates multiple clock outputs from an inexpensive 25MHz crystal or external reference clock * Frequency outputs: * * * * 25MHz Reference clock 33MHz 48MHz 127MHz PCS1P2859A Product Description The PCS1P2859A is a Precision multi-PLL based frequency synthesizer. The six Clock outputs are generated using an inexpensive 25MHz Crystal. The outputs consist of 25 MHz reference clock, 33 MHz, two 127MHz and two 48MHz clocks. The SHUTDOWNB tristates all the clocks when enabled. The device operates from a Supply Voltage of 3.3V5%V. The device is available in a 16-pin TSSOP JEDEC package for Industrial temperature range. * Zero ppm frequency synthesis error for all CLK outputs * 3.3V 5%V Supply Voltage * Low jitter design * Packaged in 16 pin TSSOP * Industrial Temperature range * Compatible with CY22393XC-F12 * Advanced low-power CMOS process Application PCS1P2859A is targeted for use in high-end multimedia, communications and consumer applications.
