Description

The PI6C106 is part of a reduced pin count two-chip clock solution for designs using an Intel BX style chipset. Companion SDRAM buffers are PI6C182 & PI6C184.

There are two PLLs, with the first PLL capable of spread spectum operation. CPU frequencies up to 100 MHz are supported.

Features

• Three CPUs @2.5V, up to 100 MHz

• Seven PCIs @ 3.3V (including one free running, 1 early)

• One 48 MHz @ 3.3V fixed

• One REF (3.3V, 14.318 MHz)

• One IOAPIC (2.5V, 14.318 MHz)

• Strong REF clock (1V/ns @50pF load)

• Excellent power management features including Power Down, PCI, and CPU stops

• Spread Spectrum for EMI control (0.5 down spread)

• Early PCI (2.5ns –700ps)

• Enhanced PCICLK4 (1.5X)

• 28-pin SSOP Packaging (H)
