The TDP0604 is a HDMI 2.0 redriver supporting data rates up to 6 Gbps. It is also backwards compatible to HDMI 1.4b. The high-speed differential inputs and outputs can be either AC-coupled or DC-coupled, which qualifies the TDP0604 to be used as a DP++ to HDMI level shifter or HDMI redriver.

The TDP0604 configuration can be programmed by pin strap or I²C. Receiver equalization, TX pre-emphasis, and TX voltage swing are controlled globally by pin-strap pins such as CTLEMAP_SEL, EQ[1:0], TXSWG, and TXPRE. In I²C mode, all transmitter and receiver settings for each lane are independently controlled. Four TDP0604 devices can be used on one I²C bus with each unique TDP0604 address set by the ADDR pin.

The TDP0604 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 TDP0604 differential output voltage levels are independent of the graphics process unit (GPU) output levels ensuring HDMI compliant levels at the receptacle. The limited redriver is a recommended mode for HDMI source applications. When configured as a linear redriver, the TDP0604 differential output levels are a linear function of the GPU output levels. Linear redriver mode is the recommended mode for sink applications.

For ease of use, the TDP0604 supports single power supply rails of 3.3 V on V_CC, integrated HPD level shifter, and DDC buffer eliminating the need for external discrete solutions.

TDP0604 supports up to 16 EQ gain options to compensate for different lengths of input cables or board traces. The EQ gain can be software adjusted by I²C control or pin strapping EQ0 and EQ1 pins. To assist in ease of implementation, the TDP0604 supports lanes swapping; see Section 8.3.4. Two temperature gradient versions of the device are available: commercial with a temperature range of 0°C to 70°C (TDP0604) and an industrial temperature range of –40°C to 85°C (TDP0604I).
