The ICS9248-195 is the single chip clock solution for Notebook designs using the 440BX, MX, VIA PM/PL/PLE 133 style chip set, with Coppermine or Tualatin processor, for Note book applications. It provides all necessary clock  ignals for such a system.

Spread spectrum of the ICS9248-195 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- 195 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
