Hi John:

Diode termination is well suited for a number of applications such as
heavily loaded buses , battery driven systems, and differential
networks.

This type of termination can limit overshoot to about 1V.

When selecting the diodes, special attention should be devoted to
several diode characteristics such as turn-on time, forward bias
voltage and reverse recovery time (all of which have to be small).

Diode termination presents some important advantages over other types
of termination. For example, no matching is required, and there is only
a minimal amount of power consumption.

There are also some disadvantages associated with this class of
termination. For instance, usually two componet are required, can be
expensive and require excessive space.

you can gain more insight regarding different types of termination, by
reviewing following article:

Ethirajan, K. and Nemec, J. "Termination Techniques for High Speed
Buses", EDN, February 16, 1998, pp. 135-143.

I hope you find this information helpful.
