Figure 2-101 • Solution 1
Solution 2
The board-level design must ensure that the reflected waveform at the pad does not exceed limits
provided in
This scheme will also work for a 3.3 V PCI/PCI-X configuration, but the internal diode should not be used
for clamping, and the voltage must be limited by the external resistors and Zener, as shown in
102. Relying on the diode clamping would create an excessive pad DC voltage of 3.3 V + 0.7 V = 4 V.
