DESCRIPTION
The TMDS261B 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. TMDS261B device is not
intended for source side applications such as external switch boxes
The TMDS261B 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).
