DESCRIPTION
The PCK2000M is a clock synthesizer/driver chip for a Pentium Pro
or other similar processors, typically used in mobile applications.
The PCK2000M has two CPU clock outputs at 2.5V. There are six
PCI clock outputs running at 33 MHz. One of the PCI clock outputs
is free–running. The 3.3V 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 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 inputs 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, except the free running PCICLK_F clock output.
The PCK2000M is available in a 28–pin SSOP package.

NOTES:
1. Clock ON/OFF latency is defined as the number of rising edges of free running PCICLKs between the clock disable goes HIGH/LOW to the
first valid clock that comes out of the device.
2. Power up latency is when PWRDWN goes inactive (HIGH) to when the first valid clocks are driven from the device.
