AD8159
APPLICATIONS INFORMATION
The main application of the AD8159 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 36 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.
Data Sheet
Another application for the AD8159 is test equipment for
evaluating high speed serial I/Os running at data rates at or
lower than 3.2 Gbps. Figure 37 illustrates the module redundancy
of a line card application. Figure 38 illustrates a possible application
of the AD8159 in a simple XAUI link tester.
