Frequency generator & integrated buffers.

ICS9248-64, Frequency Generator & Integrated Buffers

The ICS9248-64 is a main clock synthesizer chip for AMDK7 based systems.

This provides all clocks required for such a system when used with a Zero Delay Buffer Chip such as the ICS9179-06.

Spread Spectrum may be enabled by driving the SPREAD# pin active.

Spread spectrum typically reduces system EMI
