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.
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.
