The AD8159 is an asynchronous, protocol agnostic, quad-lane
2:1 switch with a total of 12 differential PECL/CML-compatible
inputs and 12 differential CML outputs. The operation of this
product is optimized for NRZ signaling with data rates up to
3.2 Gbps per lane. Each lane offers two levels of input
equalization and four levels of output pre-emphasis.
The AD8159 consists of four multiplexers and four demulti-
plexers, one per lane. Each port is a 4-lane link, and each lane
runs up to a 3.2 Gbps data rate independent of the other lanes.
The lanes are switched independently using the four select pins,
SEL[3:0]; each select pin controls one lane of the port. The
AD8159 has low latency and very low lane-to-lane skew.

Figure 1.
The main application of the AD8159 is to support redundancy
on both the backplane side and the line interface side of a serial
link. The device has unicast and bicast capability, so it is
configurable to support either 1 + 1 or 1:1 redundancy.
The AD8159 supports reversing the output and input pins on
one of its ports, which helps to connect two ASICs with
opposite pinouts.
The AD8159 is also used for testing high speed serial links by
duplicating incoming data and sending it to the destination port
and to test equipment simultaneously.
