The TMDS341A is a 3-port digital video interface (DVI) or high-definition multimedia interface (HDMI) switch that

allows up to 3 DVI or HDMI ports to be switched to a single display terminal. Four TMDS channels, one hot plug

Gbps.

The active source is selected by configuring source selectors, S1, S2, and S3. The selected TMDS inputs from

Termination resistors (50-

Ω), pulled up to V

are not required. A precision resistor is connected externally from the VSADJ pin to ground for setting the

differential output voltage to be compliant with the TMDS standard. When the output is connected to a standard

TMDS termination and OE is high, the output is high impedance.

The TMDS341A provides fixed 8-dB input equalization and selectable 3-dB output de-emphasis to optimize

system performance through 5-meter or longer DVI compliant cables. The device is characterized for operation

from 0

°C to 70°C.
