ICS280

REV G 030212

Description

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.

Using IDT’s VersaClockTM 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.

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.

Features

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

• 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

• Operating voltages of 3.3 V

• Controllable output drive levels

• Advanced, low-power CMOS process
