82541(PI/GI/EI) — Networking Silicon

NOTES:

1. Output timing measurements are as shown.

2. REQ# and GNT# signals are point-to-point and have different output valid delay and input setup times than

bussed signals. GNT# has a setup of 10 ns; REQ# has a setup of 12 ns. All other signals are bussed.

3. Input timing measurements are as shown.
