APPLICATIONS INFORMATION
The main application of the AD8158 is to support redundancy
on both the backplane side and the line interface side of a
serial link. Each port consists of four lanes to support standards
such as XAUI. Figure 43 illustrates redundancy in an XAUI
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. Also, the AD8158 can
enable module redundancy, as shown in Figure 44, and can be
used as a four-, eight- or 12-lane signal conditioning device to
enable high speed serial communication over long copper links.
