A. C. TABLES FOR A 66-MHZ BUS
The A.C. specifications given in Table 17 consist of
output delays, input setup requirements and input
hold requirements for a 66-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 200-MHz Pentium OverDrive
processor with MMX technology operation.
