PCS1P2860A May 2007 rev 0.2 Multi-Output Clock Synthesizer Features Product Description • Generates multiple clock outputs from an inexpensive The PCS1P2860A is a Precision multi-PLL based frequency synthesizer. Six Clock outputs are generated 25MHz crystal or external reference clock • Frequency outputs: using an inexpensive 25MHz Crystal or external • 25MHz Reference clock reference clock. The outputs consist of 25MHz Refout, • 125MHz 127MHz and four 125MHz clocks. SHUTDOWNB signal • 127MHz tri-states all the clocks when enabled. The device • Zero ppm frequency synthesis error for all CLK outputs operates from a Supply • 3.3V ± 5%V Supply Voltage device is available in a 16-pin TSSOP JEDEC package • Low jitter design for an Industrial temperature range. Voltage of 3.3V±5%V. The • Packaged in 16 pin TSSOP • Industrial Temperature range Application • Compatible with CY22393XC-MZ2 PCS1P2860A is targeted for use in high-end multimedia, • Advanced low-power CMOS process communications and consumer applications.
