AD8193

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 Ω and a

maximum capacitive load of 10 pF. The same select signal

(S_SEL) controls both the AD8193 and the MC74LVX4053.
