1 ±400 mV diff indicates a 400 mV amplitude signal measured between two differential nodes. The voltage swing at differential I/O pins is described in this data sheet
both in terms of the differentially measured voltage range (±400 mV diff, for example) and in terms of peak-to-peak differential swing, denoted as mV p-p diff. An
output level setting of ±400 mV diff delivers a differential peak-to-peak output voltage of 800 mV p-p diff.
THE SWITCH
(MUX/DEMUX/UNICAST/BICAST/LOOPBACK)
The mux and demux functions of the AD8155 can be controlled
either with the toggle pins or through the register map. The
multiplexer path switches received data from Input Port A or
Input Port B to Output Port C. The SEL[1:0] pins allow switching
lanes independently. The demultiplexer path switches received
data from Input Port C to Output Port A, Output Port B, or (if
bicast mode is enabled) to both Output Port A and Output Port B.

When the device is in unicast mode, the output lanes on either
Port A or Port B are in an idle state. In the idle state, the
transmitter output current is set to 0, and the P and N sides of
the lane are pulled up to the output termination voltage through
the on-chip termination resistors. To save power, the unused
receiver automatically disables.
The AD8155 supports port-level loopback, illustrated in Figure 36.
The loopback control pins override the lane select (SEL[1:0])
and bicast control (BICAST) pin settings at the port level. In serial
control mode, Bits [6:4] of Register 0x01 control loopback and
are equivalent to asserting Pin LB_A, Pin LB_B, and Pin LB_C.
Table 8 summarizes the different loopback configurations.
The loopback feature is useful for system debug, self-test, and
initialization, allowing system ASICs to compare Tx and Rx
data sent over a single bidirectional link. Loopback can also be
used to configure the device as a two- to six-lane receive
equalizer or backplane redriver.
