A. C. TABLES FOR A 50-MHZ BUS
The AC specifications of the 180/150-Pentium
OverDrive processor with MMX technology consist of
setup times, hold times, and valid delays at 0pF.
The A.C. specifications given in Table 15 consist of
output delays, input setup requirements and input
hold requirements for a 50-MHz external bus.
All A.C.
specifications (with the exception of those for the
TAP signals) are relative to the rising edge of the
CLK input.
All timings are referenced to 1.5 volts for both “0” and
“1” logic levels unless otherwise specified.
Within the
sampling window, a synchronous input must be
stable for correct 150-MHz Pentium OverDrive
processor with MMX technology running 125-MHz
operation.
