The PCK2010R has four CPU clock outputs at 2.5 V, two CPUDIV2 clock outputs running at 1/2 CPU clock frequency (66 MHz or 50 MHz depending on the state of SEL133/100) and four 3V66 clocks running at 66MHz. There are eight PCI clock outputs running at 33 MHz. One of the PCI clock outputs is free-running. 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. 56 VDD25V REF0 2 55 APIC2 REF1 3 54 APIC1 VDD3V 4 53 APIC0 XTAL_IN 5 52 VSS XTAL_OUT 6 51 VDD25V VSS 7 50 CPUDIV2_1 PCICLK_F 8 49 CPUDIV2_0 PCICLK1 9 48 VSS VDD3V 10 47 VDD25V PCICLK2 11 46 CPUCLK3 PCICLK3 12 45 CPUCLK2 VSS 13 44 VSS PCICLK4 14 43 VDD25V PCICLK5 15 42 CPUCLK1 CPUCLK0 VDD3V 16 41 PCICLK6 17 40 VSS PCICLK7 18 39 VDD3V VSS 19 38 VSS VSS 20 37 PCISTOP 3V66_0 21 36 CPUSTOP 3V66_1 22 35 PWRDWN VDD3V 23 34 SPREAD VSS 24 33 SEL1 3V66_0 25 32 SEL0 3V66_1 26 31 VDD3V VDD3V 27 30 48MHz_USB SEl133/100 28 29 VSS SW00504 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.

Period, jitter, offset and skew measured on rising edge @1.25 V for 2.5 V clocks and @ 1.5 V for 3.3 V clocks. 3. The PCICLK is the CPUCLK divided by four at CPUCLK = 133 MHz. The 3V66 CLK is internal VCO frequency divided by three at CPUCLK = 100 MHz. 4. 3V66 CLK is internal VCO frequency divided by two at CPUCLK = 133 MHz. The 3V66 CLK is internal VCO frequency divided by three at CPUCLK = 100 MHz. 5. THKH is measured at 2.0 V for 2.5 V outputs, 2.4 V for 3.3 V outputs as shown in Figure 4. 6. THKL is measured at 0.4 V for all outputs as shown in Figure 4. 7. The time is specified from when VDDQ achieves its nominal operating level (typical condition VDDQ = 3.3 V) until the frequency output is stable and operating within specification. 8. THRISE and THFALL are measured as a transition through the threshold region VOL = 0.4 V and VOH = 2.4 V (1 mA) JEDEC specification. 9. The average period over any 1 s period of time must be greater than the minimum specified period. 10. Calculated at minimum edge-rate (1V/ns) to guarantee 45/55% duty-cycle.
