Features
• Generates multiple clock outputs from an inexpensive 25MHz crystal or external reference clock • Frequency outputs: • • • 25MHz Reference clock 125MHz 127MHz
PCS1P2860A
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. operates from a Supply The device Voltage of 3.3V±5%V. The
• 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-MZ2 • Advanced low-power CMOS process
device is available in a 16-pin TSSOP JEDEC package for an Industrial temperature range.
Application
PCS1P2860A is targeted for use in high-end multimedia, communications and consumer applications.
