AD8155

APPLICATIONS INFORMATION

The main application of the AD8155 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 RXAUI. Figure 43 illustrates redundancy in an RXAUI

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 AD8155 can

enable module redundancy, as shown in Figure 44, and can be

used as a four- or six-lane signal conditioning device to enable

high speed serial communication over long copper links.
