DESCRIPTION
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 outputs
at 16.67 MHz and two 3.3 V reference clock outputs at 14.318 MHz.
All clock outputs meet Intel’s drive strength, rise/fall time, jitter,
accuracy, and skew requirements.
The part possesses dedicated power-down, CPUSTOP, and
PCISTOP input pins for power management control. These inputs
are synchronized on-chip and ensure glitch-free output transitions.
When the CPUSTOP input is asserted, the CPU clock outputs and
3V66 clock outputs are driven LOW. When the PCISTOP input is
asserted, the PCI clock outputs are driven LOW.
Finally, when the PWRDWN input pin is asserted, the internal
reference oscillator and PLLs are shut down, and all outputs are
driven LOW.
