200 MHz Spread Spectrum Clock Synthesizer/Driver

with Differential CPU Outputs

Benefits

Features

• CompliantwithIntel^®CK-Titanclocksynthesizer/driver

specifications

• Supports next-generation Pentium^®processors using

differential clock drivers

• Multiple output clocks at different frequencies

• Motherboard clock generator

— Three pairs of differential CPU outputs, up to

200 MHz

— Supports multiple CPUs and a chipset

— Support for PCI slots and chipset

— Ten synchronous PCI clocks, three free-running

— Six 3V66 clocks

— Supports AGP, DRCG reference, and Hub Link

— Supports USB host controller and graphic controller

— Supports ISA slots and I/O chip

— Two 48 MHz clocks

— One reference clock at 14.318 MHz

— One VCH clock

• Enables reduction of electromagnetic interference

(EMI) and overall system cost

• Spread Spectrum clocking (down spread)

• Enables ACPI-compliant designs

• Power-down features (PCI_STOP#, CPU_STOP#

PWR_DWN#)

• Supports up to four CPU clock frequencies

• Enables ATE and “bed of nails” testing

• Widely available standard package enables lower cost

• Three Select inputs (Mode select and IC Frequency

Select)

• OE and Test Mode support

• 56-pin SSOP package and 56-pin TSSOP package
