Texas Instruments TMDS1204 12Gbps Hybrid Redriver is an HDMI 2.1 redriver supporting data rates up to 12Gbps. It is backward compatible with HDMI 1.4b and HDMI 2.0b. The high-speed differential inputs and outputs can either be DC-coupled or AC-coupled. This feature qualifies the TMDS1204 to be used as a DP++ to HDMI level shifter or HDMI redriver. The TMDS1204 can support 3- and 4-lane HDMI 2.1 FRL at 3, 6, 8, 10, and 12Gbps.
The TMDS1204 is a hybrid redriver supporting both sink and source applications. A hybrid redriver can operate either in a limited or linear redriver function. When the TMDS1204 is configured as a limited redriver, the differential output voltage levels are independent of the graphics process unit (GPU) output levels ensuring HDMI-compliant levels at the receptacle. The limited redriver mode is recommended for HDMI source applications. When the TMDS1204 is configured as a linear redriver, the differential output levels are a linear function of the GPU output levels. This feature enables the TMDS1204 to be transparent to link training and operate as a channel shortener. Linear redriver mode is recommended for HDMI sink applications.
The Texas Instruments TMDS1204 has an integrated HPD level shifter. The HPD level shifter will shift the 5V HPD signal to either 1.8V or 3.3V. The level shifter output can also be configured for pull, push, or open drain. Integrating the level shifter eliminates discrete solutions and saves system costs. The TMDS1204 supports single power supply rails of 3.3V on VCC. It is offered in a commercial temperature (TMDS1204) and industrial temperature (TMDS1204I).
