(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.

SS
SW00892
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.

NOTES:
1. Required for board level “bed-of-nails” testing.
2. Philips center spread mode.
3. 48 MHz PLL disabled to reduce component jitter. 48 MHz outputs to be held Hi-Z instead of driven to LOW state.
4. “Normal” mode of operation.
5. TCLK is a test clock over driven on the XTALIN input during test mode. TCLK mode is based on 133 MHz CPU select logic.
6. Required for DC output impedance verification.
7. Frequency accuracy of 48 MHz must be +167 PPM to match USB default.
8. Range of reference frequency allowed is MIN = 14.316 MHz, NOMINAL = 14.31818 MHz, MAX = 14.32 MHz.

NOTES:
1. LOW means outputs held static LOW as per latency requirement below
2. ON means active.
3. PWRDWN pulled LOW, impacts all outputs including REF and 48 MHz outputs.
4. All 3V66 clocks as well as CPU clocks should stop cleanly when CPUSTOP is pulled LOW.
5. CPUDIV2, IOAPIC, REF, 48 MHz signals are not controlled by the CPUSTOP functionality and are enabled all in all conditions except when
PWRDWN is LOW.

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.

2. 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.

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
