PCK2010 CK98 100/133MHz Spread Spectrum System Clock Generator

The PCK2010 is a clock synthesizer/driver chip for a PentiumII and other similar processors. The PCK2010 has four CPU clock outputs at 2.5V, two CPUDIV2 clock outputs running at ½ CPU clock frequency (66MHz or 50MHz depending on the state of SEL133/100) and four 3V66 clocks running at 66MHz. There a.
