W320-04
200-MHz Spread Spectrum Clock Synthesizer/Driver
with Differential CPU Outputs
2W320-04
Features
Benefits
• Compliant with Intel
®
CK-Titan clock synthesizer/driver Supports next-generation Pentium
®
processors using
specifications
differential clock drivers
• Multiple output clocks at different frequencies
— Three pairs of differential CPU outputs, up to 200 MHz
— Ten synchronous PCI clocks, three free-running
— Six 3V66 clocks
— Two 48-MHz clocks
— One reference clock at 14.318 MHz
— One VCH clock
• Spread Spectrum clocking (down spread)
• Power-down features (PCI_STOP#, CPU_STOP#
PWR_DWN#)
• Three Select inputs (Mode select and IC Frequency
Select)
• OE and Test Mode support
• 56-pin SSOP package and 56-pin TSSOP package
Enables reduction of electromagnetic interference (EMI)
and overall system cost
Enables ACPI-compliant designs
Supports up to four CPU clock frequencies
Enables ATE and “bed of nails” testing
Widely available standard package enables lower cost
Motherboard clock generator
— Supports multiple CPUs and a chipset
— Support for PCI slots and chipset
— Supports AGP, DRCG reference, and Hub Link
— Supports USB host controller and graphic controller
— Supports ISA slots and I/O chip
