DATASHEET

TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER ICS280

Description

Features

The ICS280 field programmable spread spectrum clock

synthesizer generates up to four 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 four reference outputs

Using IDT’s VersaClock software to configure PLLs and

outputs, the ICS280 contains a One-Time Programmable

(OTP) ROM for field programmability. Programming

features include input/output frequencies, spread spectrum

amount and eight selectable configuration registers.

• Operating voltages of 3.3 V

• Controllable output drive levels

• Advanced, low-power CMOS process

• Available in RoHS compliant packaging

NOTE: EOL for non-green parts to occur on 5/13/10

per PDN U-09-01

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 ICS280 is also available in factory programmed custom

versions for high-volume applications.
