General Description

The ICS9148-60 is part of a reduced pin count two-chip clock solution for designs using an Intel BX style chipset. Companion SDRAM buffers are ICS9179-11 and -12.

There are two PLLs, with the first PLL capable of spread spectrum operation. Spread spectrum typically reduces system EMI by 8-10dB. The second PLL provides support for USB(48MHz) and 24MHz requirements. CPU frequencies up to 100MHz are supported.
