15 Signal Switching Characteristics
The AMD-K6-2E processor signal switching characteristics are
presented in tables 56 through 65. Valid delay, float, setup, and
hold timing specifications are listed. These specifications are
provided for the system designer to determine if the timings
necessary for the processor to interface with the system logic
are met.
s Table 56 and Table 57 on page 268 contain the switching
characteristics of the CLK input.
s Table 58 through Table 61, beginning on page 270, contain
the timings for the normal operation signals.
s Table 62 on page 278 and Table 63 on page 279 contain the
timings for RESET and the configuration signals.
s Table 64 and Table 65 on page 280 contain the timings for
the test operation signals.
All signal timings provided are:
s Measured between CLK, TCK, or RESET at 1.5 V and the
corresponding signal at 1.5 V—this applies to input and
output signals that are switching from Low to High, or from
High to Low
s Based on input signals applied at a slew rate of 1 V/ns
between 0 V and 3 V (rising) and 3 V to 0 V (falling)
s Valid within the operating ranges given in “Operating
Ranges” on page 254
s Based on a load capacitance (C_L) of 0 pF

CLK Switching Characteristics
Table 56 and Table 57 contain the switching characteristics of
the CLK input to the AMD-K6-2E processor for 100-MHz and
66-MHz bus operation, respectively, as measured at the voltage
levels indicated by Figure 89 on page 269.
The CLK Period Stability parameter specifies the variance
(jitter) allowed between successive periods of the CLK input
measured at 1.5 V. This parameter must be considered as one of
the elements of clock skew between the AMD-K6-2E and the
system logic.
