AMD Athlon Processor Model 4 Data Sheet
Preliminary Information
The AC characteristics of the AMD Athlon system bus are
shown in Table 12 on page 31. The parameters are grouped
based on the source or destination of the signals involved.

Notes:
1. Rise and fall time ranges are guidelines over which the I/O has been characterized.
2. TSKEW-SAMEEDGE is the maximum skew within a clock forwarded group between any two signals or between any signal and
its forward clock, as measured at the package, with respect to the same clock edge.
TSKEW-DIFFEDGE is the maximum skew within a clock forwarded group between any two signals or between any signal and
its forward clock, as measured at the package, with respect to different clock edges.
3. Input SU and HD times are with respect to the appropriate Clock Forward Group input clock.
4. The synchronous signals include
PROCRDY, CONNECT, CLKFWDRST.
5. TVAL is RSTCLK rising edge to output valid for PROCRDY. Test Load is 25pF.
6. TSU is setup of CONNECT/CLKFWDRST to rising edge of RSTCLK. THD is hold of CONNECT/CLKFWDRST from rising edge
of RSTCLK.
