Pentium III Processor for the SC242 at 450 MHz to 800 MHz
NOTES:
1. BCLK period is 7.5 ns.
2. These values are specified at the processor core pins.
3. Overshoot/Undershoot Magnitude = 2.3 V is an absolute value and should never be exceeded.
4. Overshoot is measured relative to VSS, while undershoot is measured relative to VTT.
5. Overshoot/Undershoot Pulse Duration is measured relative to 1.635 V.
NOTES:
1. PICCLK period is 30 ns.
2. This table applies to all 1.5 V tolerant non-AGTL+ signals. BCLK, PICCLK, and PWRGOOD are the only non-
AGTL+ signals that are 2.5 V tolerant at the processor core pins.
3. These values are specified at the processor core pins.
4. Overshoot/Undershoot Magnitude = 2.3 V is an absolute value and should never be exceeded.
5. Overshoot is measured relative to VSS, while undershoot is measured relative to VTT.
6. Overshoot/Undershoot Pulse Duration is measured relative to 1.635 V.
