| PCS1P2860A Multi-Output Clock Synthesizer Features * Generates multiple clock outputs from an inexpensive 25MHz crystal or external reference clock * Frequency outputs: o 25MHz Reference clock o 125MHz o 127MHz * Zero ppm frequency synthesis error for all CLK outputs * 3.3V 5%V Supply Voltage * Low jitter design * Packaged in 16-pin TSSOP * Compatible with CY22393XC-MZ2 * Advanced CMOS process Product Description The PCS1P2860A is a Precision multi-PLL based frequency synthesizer. Six Clock outputs are generated using an inexpensive 25MHz Crystal or external reference clock. The outputs consist of 25MHz Refout, 127MHz and four 125MHz clocks. SHUTDOWNB signal tri-states all the clocks when enabled. The device operates from a Supply Voltage of 3.3V 5%V. The device is available in a 16-pin TSSOP JEDEC package. Application PCS1P2860A is targeted for use in high-end multimedia, communications and consumer applications.
