The TMDS1204 is an HDMI 2.1 redriver supporting data rates up to 12Gbps. It is backwards compatible for HDMI 1.4b and HDMI 2.0b. The high-speed differential inputs and outputs can either be AC-coupled or DC-coupled, which qualifies the TMDS1204 to be used as a DP++ to HDMI level shifter or HDMI redriver. The TMDS1204 can support both 3 and 4 lane HDMI 2.1 FRL at 3, 6, 8, 10, and 12Gbps.
The TMDS1204 is a hybrid redriver supporting both source and sink applications. A hybrid redriver can operate either in a linear or limited redriver function. When configured as a limited redriver, the TMDS1204 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 configured as a linear redriver, the TMDS1204 differential output levels are a linear function of the GPU output levels enabling TMDS1204 to be transparent to link training and operate as a channel shortener. Linear redriver mode is recommended for HDMI sink applications.
The 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 push, pull, or open-drain. The integration of the level shifter eliminates discrete solutions and thereby saves system cost.
The TMDS1204 supports single power supply rails of 3.3V on VCC and is offered in a commercial temperature (TMDS1204) and industrial temperature (TMDS1204I).
