The TMDS361B is a three-port digital video interface (DVI) or high-definition multimedia interface (HDMI) switch that allows up to three DVI or HDMI ports to be switched to a single display terminal. Four TMDS channels, one hot-plug detector, and a digital display control (DDC) interface are supported on each port. Each TMDS channel supports signaling rates up to 3 Gbps to allow 1080p resolution in 16-bit color depth. TMDS361B is not intended for source side applications such as external switch boxes.

The TMDS361B provides an adaptive equalizer for different ranges of cable lengths. The equalizer automatically compensates for intersymbol interference [ISI] loss of an HDMI/DVI cable for up to 20 dB at 3 Gbps.

When any of the input ports are selected, the integrated terminations (50- termination resistors pulled up to VCC) are switched on for the TMDS clock channel, the TMDS clock-detection circuit is enabled, and the DDC repeater is enabled.
