AD8194
Rev. 0 | Page 15 of 16
Figure 26 shows the layout of the TMDS traces. These are 100 Ω
differential, controlled-impedance traces. Serpentine traces are
used for some of the paths to match the lengths within a group
of four. The gray traces are routed on the top layer and the black
traces on the bottom layer.
The low speed switching is performed by an MC74LVX4053.
This part contributes a maximum on resistance of 108  and a
maximum capacitive load of 10 pF. The same select signal
(S_SEL) controls both the AD8194 and the MC74LVX4053.

THE AD8194 HAS A CONDUCTIVE HEAT SLUG TO HELP DISSIPATE HEAT AND ENSURE RELIABLE OPERATION OF
THE DEVICE OVER THE FULL HDMI/DVI TEMPERATURE RANGE. THE SLUG IS EXPOSED ON THE BOTTOM OF
THE PACKAGE AND ELECTRICALLY CONNECTED TO AVEE. IT IS RECOMMENDED THAT NO PCB SIGNAL TRACES
OR VIAS BE LOCATED UNDER THE PACKAGE THAT COULD COME IN CONTACT WITH THE CONDUCTIVE SLUG.
ATTACHING THE SLUG TO AN AVEE PLANE REDUCES THE JUNCTION TEMPERATURE OF THE DEVICE WHICH MAY
BE BENEFICIAL IN HIGH TEMPERATURE ENVIRONMENTS.
