DESCRIPTION
The PCK2010 is a clock synthesizer/driver chip for a PentiumII and
other similar processors.
The PCK2010 has four CPU clock outputs at 2.5V, two CPUDIV2
clock outputs running at CPU clock frequency (66MHz or 50MHz
depending on the state of SEL133/100) and four 3V66 clocks
running at 66MHz. There are eight PCI clock outputs running at
33MHz. One of the PCI clock outputs is free-running. Additionally,
the part has three 2.5V IOAPIC clock outputs at 16.67MHz and two
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 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.
