DESCRIPTION
The PCK2000 is a clock synthesizer/driver chip for a Pentium Pro or
other similar processors.
The PCK2000 has four CPU clock outputs at 2.5V. There are eight
PCI clock outputs running at 33MHz. One of the PCI clock outputs is
free-running. Additionally, the part has two 3.3V USB clock outputs
at 48MHz, two 2.5V IOAPIC clock outputs at 14.318MHz, and three
3.3V reference clock outputs at 14.318MHz. All clock outputs meet
Intel’s drive strength, rise/fall time, jitter, accuracy, and skew
requirements.
The part possesses dedicated powerdown, 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 are
driven LOW. When the PCISTOP input is asserted, the PCI clock
outputs are driven LOW, except for free running PCICLK_F clock
output..
Finally, when the PWRDWN input pin is asserted, the internal
reference oscillator and PLLs are shut down, and all outputs are
driven LOW.
The PCK2000 is available in a 48–pin SSOP package.
