General Description
The ICS9250-26 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 ICS9250-26 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
Features:
? Supports spread spectrum modulation, down spread 0 to -0.5 and ± 0.25 center spread.
? I2C support for power management
? Efficient power management scheme through PD#
? Uses external 14.138 MHz crystal
? Alternate frequency selections available through I2C control.
Output Features:
? 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) @ 33.3 MHz
? 2 Hublink clocks (3.3 V) @ 66.6 MHz
? 2 USB (3.3V) @ 48 MHz ( Non spread spectrum)
? 1 REF (3.3V) @ 14.318 MHz
Recommended Application:
810/810E type chipset. Provides three CPU speeds (66.6, 100, 133MHz) with SDRAM = 133.3MHz.
