PCK2014A CK98 100/133 MHz spread spectrum system clock generator

PCK2014A CK98 100/133 MHz spread spectrum system clock generator

The PCK2014A is a clock generator (frequency synthesizer) chip for a Pentium III and other similar processors. The PCK2014A has six CPU clock outputs at 2.5 V, two 3V66 clocks running at 66 MHz. there are six PCI clock outputs running at 33 MHz. Additionally, the part has three 2.5 V IOAPIC clock ou.
