The TMDS261 is a two-port digital video interface (DVI) or high-definition multimedia interface (HDMI) switch that

allows up to two 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.

The TMDS261 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 (see

Figure 15).
