PRELIMINARY DATASHEET

TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER ICS281

Description

Features

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.

• Packaged as 16-pin TSSOP

• Eight addressable registers

• Replaces multiple crystals and oscillators

• Output frequencies up to 200 MHz at 3.3 V

• Configurable Spread Spectrum Modulation

• Input crystal frequency of 5 to 27 MHz

• Input clock frequency of 3 to 166 MHz

• Up to three reference outputs

• Operating voltages of 3.3 V

• VDDO output control from 1.8 V to 3.3 V

• Controllable output drive levels

Using ICS’ 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.

• Advanced, low-power CMOS process

• Available in Pb (lead) free packaging

The ICS281 is also available in factory programmed custom

versions for high-volume applications.
