PCK2010R

INTEGRATED CIRCUITS PCK2010R CK98R (100/133MHz) RCC spread spectrum system clock generator Product specification 1999 Oct 19 Philips Semiconductors Philips Semiconductors Product specification CK98R (100/133MHz) RCC spread spectrum system clock generator 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.
