PI6C106 Pentium/Pro System Clock Chip Datasheet

PI6C106 Pentium/Pro System Clock Chip

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. Frequency Table SEL 100/66.6# 1 0 CPU M Hz 100 66.6 PCI M Hz 33.3 33.3 Block D.
