Advance Information
Third party brands and names are the property of their respective owners.
General Description
The ICS9248-189 is a main clock synthesizer chip for AMD-K7 based note book systems with VIA style chipset. This provides
all clocks required 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 ICS9248-189 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.
Pin Descriptions
Notes:
1:
Internal Pull-up Resistor of 120K to 3.3V on indicated inputs
2:
Bidirectional input/output pins, input logic levels are latched at internal power-on-reset. Use 10Kohm resistor
to program logic Hi to VDD or GND for logic low.
