ICS9250-08
0378I—07/17/03
General Description
The ICS9250-08 is the single chip clock solution for
Desktop/designs using BX, Appollo Pro 133 type of chip
sets. It provides all necessary clock signals for such a
system.
Spread spectrum may be enabled through I
2C
programming.
Spread spectrum typically reduces system EMI by 8dB to
10dB. This simplifies EMI qualification without resorting
to
board design iterations or costly shielding. The ICS9250-
08
employs a proprietary closed loop design, which tightly
controls the percentage of spreading over process and
temperature variations.
Serial programming I
2C interface allows changing functions,
stop clock programming and frequency selection.
Power Groups
VDDREF = REF [1:0], X1, X2
VDDPCI = PCICLK_F, PCICLK [5:0]
VDDSDR = SDRAM [15:0], supply for PLL core,
VDD48 = 48MHz, 24MHz
VDDLIOAPIC = IOAPIC_F
VDDLCPU = CPUCLK_F [2:1]
