产品说明

The SN75DP126 switches one Dual-Mode DisplayPort (DP++) input to one Dual-Mode DisplayPort (DP++) sink output or one HDMI/DVI sink output. The HDMI/DVI output has a built-in level translator compliant with DVI 1.0 and HDMI 1.4b standard TMDS signaling, and is specified up to a maximum data rate of 3.4 Gbps, supporting resolutions greater than 1920 X 1440 and HDTV deep color at 1080p. An integrated DP-HDMI Adaptor ID buffer can be accessed when the HDMI/DVI sink is selected to indicate support for HDMI signaling.

The device compensates for PCB-related frequency loss and switching-related loss to provide the optimum electrical performance from source to sink. The DP++ Main Link signal inputs feature-configurable equalizers with selectable boost settings.

At the SN75DP126 DP++ Main Link output, four primary levels of differential output voltage (VOD) swing and four primary levels of pre-emphasis are available as well as a secondary level of boost adjustment, programmed through I2C, for fine-tuning the Main Link output. The device can monitor the AUX channel and automatically adjust output signaling levels and input equalizers based on DP Link Training commands.
