DATASHEET

TRIPLE PLL FIELD PROGRAMMABLE VCXO CLOCK SYNTHESIZER

ICS276

Description

Features

The ICS276 field programmable VCXO 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 and crystal oscillators 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

• Input crystal frequency of 5 to 27 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 IDT’s VersaClock software to configure PLLs and

outputs, the ICS276 contains a One-Time Programmable

(OTP) ROM for field programmability. Programming

features include VCXO and eight selectable configuration

registers.

• Advanced, low-power CMOS process

• Available in Pb (lead) free packaging

Each of the outputs are powered by a single 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 VCXOs, multiple crystals

and oscillators, saving board space and cost.

NOTE: EOL for non-green parts to occur on

5/13/10 per PDN U-09-01

The ICS276 is also available in factory programmed custom

versions for high-volume applications.
