GNDSDR, VDDSDR = SDRAM [7:0], SDRAM_F,
supply for PLL core
GND3V66,VDD3V66=3V66

VDDLAPIC = IOAPIC
GNDLCPU , VDDLCPU = CPUCLK [1:0]
The ICS9248-112 is the single chip clock solution for designs
using the 810/810E style chipset. It provides all necessary
clock signals for such a system.
Spread spectrum may be enabled through I2C 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 ICS9248-112
employs a proprietary closed loop design, which tightly
controls the percentage of spreading over process and
temperature variations.
Serial programming I2C interface allows changing functions,
stop clock programming and frequency selection.
