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.
