Features
Benefits
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)
Supports next-generation Pentium
processors using differ-
ential 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
Power-down features (PCI_STOP#, CPU_STOP#
PWR_DWN#)
Three Select inputs (Mode select & IC Frequency Select)
Supports up to four CPU clock frequencies
OE and Test Mode support
56-pin SSOP package and 56-pin TSSOP package
Enables ATE and “bed of nails” testing
Widely available, standard package enables lower cost
