TMDS261BPAG (TEXAS INSTRUMENTS)

The TMDS261BPAG is a 2-port Digital Video Interface (DVI) or High-Definition Multimedia Interface (HDMI) Switch 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 3Gbps to allow 1080p resolution in 16-bit color depth. TMDS261B device is not intended for source side applications such as external switch boxes. It 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 20dB at 3Gbps. When any of the input ports are selected, the integrated terminations (50R 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.
