ICS9248-143
Byte0: Functionality and Frequency Select Register (default = 0)
Serial Configuration Command Bitmap
Notes:
1, Default at Power-up will be for latched logic inputs to define frequency. Bit [2, 6:4] are default to 0011.
2, PWD = Power-Up Default
The ICS9248-143 is the single chip clock solution for Notebook designs using thE 440BX, MX, VIAApollo Pro 133,Apollo Pro
Media or MVP4 style chip set. 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 ICS9248-143 employs a
proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
