The TMDS461 is a 4-port digital video interface (DVI) or high-definition multimedia interface (HDMI) switch that
allows up to four 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 TMDS461 provides an analog 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 19 ).
