Features
Multiple output clocks at different frequencies
— Four pairs of differential CPU outputs, up to 133 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#, PD#)
Three Select inputs (Mode select & IC Frequency
Select)
OE and Test Mode support
56-pin SSOP package and 56-pin TSSOP package
Benefits
Motherboard clock generator
— Support Multiple CPUs and a chipset
— Support for PCI slots and chipset
— Supports AGP and Hub Link
— Supports USB host controller and graphic controller
— Supports ISA slots and I/O chip
Enables reduction of 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
