ICS9248-77 Frequency Timing Generator

The ICS9248-77 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 Direct Rambus Clock Generator(DRCG) chip such as the ICS9212-01. Spread Spectrum may be enabled by driving the SPRE.

ICS9248-77 Features

* Generates the following system clocks: - 3 - CPUs @ 2.5V, up to 150MHz. - 3 - IOAPIC @ 2.5V, PCI or PCI/2 - 3 - 3V66MHz @ 3.3V. - 11 - PCIs @ 3.3V. - 1 - 48MHz, @ 3.3V fixed. - 1 - 24MHz, @ 3.3V fixed. - 1 - CPU/2, @ 2.5V. ± .25% center spread, or 0 to -.5% down spread. Uses external 14.318MHz
