Pentium
®
III Processor for the PGA370 Socket at 500 MHz to 1.13 GHz
NOTES:
1. Unless otherwise noted, all specifications in this table apply to Pentium III processors at all frequencies.
2. Parameter measured at 9 mA (for use with TTL inputs).
3. (0 ≤ V
IN ≤ 2.5 V +5%); (0 ≤ VOUT ≤ 2.5 V +5%).
4. For BCLK specifications, refer to Table 24 on page 51.
5. (0 ≤ V
IN ≤ 1.5 V +3%); (0 ≤ VOUT ≤ 1.5 V +3%).
6. Applies to non-AGTL+ signals except BCLK, PICCLK, and PWRGOOD.
7. Applies to non-AGTL+ signals except BCLK, PICCLK, and PWRGOOD.
8. For Coppermine-T differential clocking, the input low voltage is (VCMOS_REF - 0.300)V.
