TMDS1204IRNQR

Specialized Overview

The TMDS1204IRNQR is a Texas Instruments HDMI 2.1 hybrid redriver supporting data rates up to 12 Gbps with backward compatibility for HDMI 1.4b and 2.0b. It accommodates both AC-coupled and DC-coupled high-speed differential inputs and outputs, enabling use as a DP++ to HDMI level shifter or HDMI redriver. The device supports HDMI 2.1 fixed rate link (FRL) configurations of 3, 6, 8, 10, and 12 Gbps across three and four lanes. Operating on a single 3.3V power supply, it features an integrated HPD level shifter compatible with 1.8V and 3.3V LVCMOS levels. The component is housed in a 40-pin, 0.4mm pitch, 4mm × 6mm WQFN package and operates within the industrial temperature range of -40°C to 85°C.

Specialized Feature Summary

• Hybrid redriver architecture supporting both linear and limited modes for source and sink applications
• Integrated adaptive and fixed equalizer providing up to 12 dB gain at 6 GHz
• Built-in hot plug detect (HPD) level shifter eliminating discrete solution requirements
• Configurable via I2C interface or pin-strap settings for flexible system integration

Specialized Applications

• Notebooks and desktops
• TV systems
• Home theater and entertainment equipment
• Gaming systems
• Docking stations

Specialized Procurement Notes

Verify the complete part number TMDS1204IRNQR against official Texas Instruments documentation to confirm the 'I' suffix denotes the industrial temperature grade (-40°C to 85°C). Ensure the 'RNQR' suffix corresponds to the specified 40-pin WQFN package and reel quantity. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin functions prior to finalizing procurement specifications.

Specialized Selection Notes

Select this component when designing HDMI 2.1 interfaces requiring support for FRL modes up to 12 Gbps. The industrial temperature rating makes it suitable for environments exceeding standard commercial limits. Consider the integrated HPD level shifter if system design constraints prohibit external discrete components. Verify that the application requires either AC or DC coupling compatibility, as the device supports both input/output configurations.

Specialized Part Context

The TMDS1204 series includes the commercial grade variant TMDS1204RNQ, which operates from 0°C to 70°C. The TMDS1204IRNQR specifically extends the operating range to -40°C to 85°C for industrial reliability. Both variants share identical functional capabilities, including 12 Gbps data rate support and hybrid redriver features, differing primarily in thermal performance and environmental tolerance ratings.
