APPLICATIONS INFORMATION

The main application of the AD8153 is to support redundancy

on both the backplane side and the line interface side of a serial

link. Figure 34 illustrates redundancy in a typical backplane

system. Each line card is connected to two switch fabrics

(primary and redundant). The device can be configured to

support either 1 + 1 or 1:1 redundancy.

Data Sheet

Another application for the AD8153 is in test equipment for

evaluating high speed serial links. Figure 36 illustrates a

possible application of the AD8153 in a simple link tester.
