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.

NOTES: 1. VDD and VSS names in the above tables reflects a likely internal POWER and GROUND partition to reduce the effects of internal noise on the performance of the device. In reality, the platform will be configured with the VDDAPIC and VDDCPU pins tied to a 2.5V supply, all remaining VDD pins tied to a common 3.3V supply and all VSS pins being common.

NOTES: 1. See Figure 3 for measure points. 2. Period, jitter, offset, and skew are measured on the rising edge @ 1.25V for 2.5V clocks and @ 1.5V for 3.3V clocks. 3. The PCICLK is the CPUCLK divided by two at CPUCLK = 66.6MHz. PCICLK is the CPUCLK divided by three at CPUCLK = 100MHz. 4. The CPUCLK must always lead the PCICLK as shown in Figure 2. 5. THKH is measured @ 2.0V as shown in Figure 4. 6. THKL is measured @ 0.4V as shown in Figure 4. 7. The time is specified from when VDDQ achieves its nominal operating level (typical condition is VDDQ = 3.3V) until the frequency output is stable and operating within specification. 8. Defined as once the clock is at its nominal operating frequency, the adjacent period changes cannot exceed the time specified. 9. THRISE and THFALL are measured as a transition through the threshold region VOL = 0.4V and VOH = 2.0V (1mA) JEDEC specification. 10. THRISE and THFALL (48MHz, REF, PC) are measured as a transition through the threshold region VOL = 0.4V and VOH = 2.4V
