Description

PC MAIN CLOCK
The ICS953401 is a two chip clock solution for desktop designs using SIS 656/662 style chipsets. When used with a zerodelay buffer such as the ICS9P931 for DDR applications ICS953401 provides all the necessary clocks signals for such a system.

ICS953401 Output Features:

2 - Pairs of differential CPUCLKs (differential current mode)

1 - Pair of differential SRCCLK (differential currentmode)

5 - Pairs of differential PCI-Express clocks

8 - PCI @ 3.3V, 2 free-running

2 - ZCLKs @ 3.3V

1- 12/48MHZ @ 3.3V selectable by I2C

1- 24/48MHz, @ 3.3V selectable by I2C

3 - REF @ 3.3V, 14.318MHz.
