AV9248F-151 Datasheet PDF - Integrated Circuit Systems

General Description
The ICS9248-151is a single chip clock solution for Desktop designs. It provides all necessary clock signals for such a system. Spread spectrum may be enabled through I2 C 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 ICS9248-151 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.

FEATUREs:
• Up to 200MHz frequency support
• Support power management: PCI, CPU stop and Power Down.
• Spread spectrum for EMI control (0 to -0.5%, ± 0.25%).
• Uses external 14.318 MHz crystal
