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

General Description

The PCK2010R is a clock generator (frequency synthesizer) chip for a Pentium II and other similar processors.

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.
