Pentium/ProTM System Clock Chip

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 sy
