ICS9248-66, Frequency Generator & Integrated Buffers
The ICS9248-66 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 ICS9211-01.
Spread Spectrum may be enabled by driving the SPRE
