PRELIMINARY DATASHEET

TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER

ICS291

Description

The ICS291 field programmable spread spectrum clock

synthesizer generates up to six 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 ICS’ VersaClock

software to configure PLLs and

outputs, the ICS291 contains a One-Time Programmable

(OTP) ROM for field programmability. Programming

features include input/output frequencies, spread spectrum

amount, eight selectable configuration registers and up to

two sets of three low-skew outputs.

Each of the two output groups are powered by a separate

VDDO voltage. VDDO may vary from 1.8 V to VDD.

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 ICS291 is also available in factory programmed custom

versions for high-volume applications.
