200-MHz Spread Spectrum Clock Synthesizer/Driver
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 & 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 Support 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
