EVM Configuration and Description
4.1
EVM Description
To conform to the HDMI specification, all four differential pairs on the board are impedance matched to a
100-Ω differential. The trace length of the through-path and the trace length through the TS3USB3031
switch are also matched for comparison purposes. The printed-circuit board (PCB) is a four-layer, top-side
populated board (see the schematic and PCB layout in
of the hardware design are detailed in the following sections.
NOTE: The dielectric material between the signal and GND plane is Rogers 4350B. This is a high-
performance PCB material and if FR-4 is used under the same conditions, the same results
should not be expected due to the board losses of FR-4.
