PCK2010R CK98R 100/133MHz RCC spread spectrum system clock generator

The PCK2010R is a clock generator (frequency synthesizer) chip for a Pentium II and other similar processors. The PCK2010R has four CPU clock outputs at 2.5 V, two CPUDIV2 clock outputs running at ½ CPU clock frequency (66 MHz or 50 MHz depending on the state of SEL133/100) and four 3V66 clocks runn.

PCK2010R Features

* Mixed 2.5 V and 3.3 V operation

* Four CPU clocks at 2.5 V

* Eight PCI clocks at 3.3 V, one free-running (synchronous with CPU clocks) Finally, when the PWRDWN input pin is asserted, the internal reference oscillator and PLLs are shut down, and all outputs are driven LOW.
