The ICS9250-16 is a single chip clock solution for 810/810E type chipset. It provides all necessary clock signals for such a system. Spread spectrum may be enabled through I2C programming. Spread spectrum typically reduces EMI by 8dB to 10 dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9250-16 e.
• 3 CPU (2.5V) 66.6/133.3MHz (up to 150MHz achievable through I2C)
• 9 SDRAM (3.3V) @ 133.3MHz (up to 150MHz achievable through I2C)
• 8 PCI (3.3 V) @33.3MHz
• 2 IOAPIC (2.5V) @ 33.3MHz
• 2 Hublink clocks (3.3 V) @ 66.6MHz
