ICS9250-28 buffers equivalent, frequency generator & integrated buffers.
* 2 CPU (2.5V) (up to 133MHz achievable through I2C)
* 13 SDRAM (3.3V) (up to 133MHz achievable through I2C)
* 2 PCI (3.3 V) @33.3MHz
* 1 IOAPIC (2.5V) @.
The ICS9250-28 is part of a two chip clock solution for 810/810E and 815 type chipset. Combined with the ICS9112-17, the ICS9250-28 provides all necessary clock signals for such a system. Spread spectrum may be enabled through I2C programming. Spread.
