PI6C106 - Pentium/Pro System Clock Chip

General 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.

Key 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 S.
