General Description
The ICS9248-107 is a main clock synthesizer chip for Pentium II based systems using Rambus Interface DRAMs.
This chip provides all the clocks required for such a system when used with a zero delay buffer such as the ICS9179-06.
Spread Spectrum may be enabled through I2C.
Key Features
- 4 - CPUs @ 2.5V, up to 180MHz.
- 3 - IOAPIC @ 2.5V.
- 3 - 3V66MHz @ 3.3V.
- 11 - PCIs @ 3.3V.
- 1 - 48MHz, @ 3.3V fixed.
- 1 - 24/48MHz, @ 3.3V Features:.
- Up to 180MHz frequency support.
- Use a zero delay buffer such as the ICS9179-06 to generate SDRAM clocks. Support power management: Power down Mode from I2C programming. Spread spectrum for EMI control ± 0.25% center spread). Uses external.
