200 MHz Spread Spectrum Clock Synthesizer/Driver with Differential CPU Outputs
Features
Compliant with Intel CK-Titan clock synthesizer/driver specifications 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
Benefits
Supports next-generation Pentium processors using differential clock drivers 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 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
