Multi-Output Clock Synthesizer
PCS1P2860A
Features
Generates multiple clock outputs from an inexpensive
25MHz crystal or external reference clock
Frequency outputs:
25MHz Reference clock
125MHz
127MHz
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
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
for an Industrial temperature range.
Application
PCS1P2860A is targeted for use in high-end multimedia,
communications and consumer applications.
