TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER

ICS281

Description

The ICS281 field programmable spread spectrum clock

synthesizer generates up to three high-quality,

high-frequency clock outputs including multiple reference

clocks from a low-frequency crystal input. It is designed to

replace crystals, crystal oscillators and stand alone spread

spectrum devices in most electronic systems.

Using IDT’s VersaClock

software to configure PLLs and

outputs, the ICS281 contains a One-Time Programmable

(OTP) ROM for field programmability. Programming

features include input/output frequencies, spread spectrum

amount and eight selectable configuration registers.

Using Phase-Locked Loop (PLL) techniques, the device

runs from a standard fundamental mode, inexpensive

crystal, or clock. It can replace multiple crystals and

oscillators, saving board space and cost.

The ICS281 is also available in factory programmed custom

versions for high-volume applications.

Features

•

Packaged as 16-pin TSSOP – Pb-free, RoHS compliant
