PCK2010R Datasheet Ck98r 100/133mhz Rcc Spread Spectrum System Clock Generator

Manufacturer: NXP Semiconductors

Overview: 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.

General Description

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 running at 66MHz.

There are eight PCI clock outputs running at 33 MHz.

Key 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. PIN.
