AD8192
APPLICATIONS INFORMATION
The AD8192 is an HDMI/DVI switch featuring equalized TMDS
inputs, pre-emphasized TMDS outputs, and buffered auxiliary
signals. It is intended for use as a 2:1 switch in systems with long
cable runs on both the input and/or the output, and is fully
HDMI 1.3a transmit and receive compliant.
PINOUT
By default, the AD8192 is designed to have an HDMI/DVI
receiver pinout at its input and a transmitter pinout at its
output. However, the input/output mapping of the AD8192 is
completely programmable via the serial control interface. This
allows a designer to integrate the AD8192 into virtually any
application without requiring the use of vias on the TMDS
traces in the PCB layout.
In addition to 12 dB of input equalization, the AD8192 provides
up to 6 dB of output pre-emphasis that boosts the output TMDS

signals and allows the AD8192 to precompensate when driving
long PCB traces or output cables. The net effect of the input
equalization and output pre-emphasis of the AD8192 is that the
AD8192 can compensate for the signal degradation of both input
and output cables; it acts to reopen a closed input data eye and
transmit a full swing HDMI signal to an end receiver.
The AD8192 also provides a distinct advantage in receive-type
applications because it is a fully buffered HDMI/DVI switch;
the AD8192 fully buffers and electrically decouples the outputs
from the inputs for both the TMDS and the auxiliary lines. There-
fore, the effects of any vias placed on the output signal lines are
not seen at the input of the AD8192. The programmable output
terminations also improve signal quality at the output of the
AD8192. Thus, the PCB designer has significantly increased
flexibility in the placement and routing of the output signal path
with the AD8192 over other solutions.
