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
