PCK2000 Datasheet (NXP) - CK97 66/100MHz System Clock Generator

PCK2000, CK97 66/100MHz System Clock Generator

The PCK2000 is a clock synthesizer/driver chip for a Pentium Pro or other similar processors.

The PCK2000 has four CPU clock outputs at 2.5V.

There are eight PCI clock outputs running at 33MHz.

One of the PCI clock outputs is free-running.

Additionally, the part has two 3.3V USB clock outputs at 48M
