Product details
Overview
TDES4940RURR from Texas Instruments is a V3Link Enhanced Video to Embedded DisplayPort bridge deserializer IC that converts high-speed serialized video over coax/STP into VESA-compliant eDP v1.4b output. It supports 4K @ 60 Hz (30-bit color), HBR3 link rate (8.1 Gbps/lane), dual-channel V3Link up to 27 Gbps, integrated HDCP v1.4, and operates from 1.8V/1.15V supplies in automotive-grade temperature range (–20°C to +85°C). It enables compact, low-EMI display interconnects in medical and infotainment HMIs.
For engineers reviewing the TDES4940RURR datasheet, TDES4940RURR pinout, TDES4940RURR application, or TDES4940RURR equivalent, key selection criteria include V3Link channel count support, eDP transmitter compliance (v1.4b/HBR3), HDCP v1.4 integration, thermal rating (–20°C to +85°C), and VQFNP-88 package compatibility with high-density PCB layouts.
Technical Context
The TDES4940RURR implements a full V3Link Enhanced Video deserialization pipeline with adaptive equalization for coax/STP channels operating at 3.375–13.5 Gbps per lane, plus independent eDP v1.4a/b transmitter logic supporting 1/2/4-lane main links at HBR3/HBR2/HBR/RBR rates. Its control channel integrates dual fast-mode-plus I²C buses (up to 1 MHz) and GPIO-based SPI/UART pass-through.
It embeds hardware-level security features including on-chip HDCP v1.4 keys, ECC on control bits, CRC error diagnostics, BIST, and unique ID for anti-counterfeiting - all coordinated under a unified low-power architecture using 1.8V and 1.15V rails and qualified to ISO 10605/IEC 61000-4-2 ESD standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar V3Link-to-eDP bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSER953RURR | Serializer companion in same family; not a deserializer - cannot replace TDES4940RURR functionally | Used on source side only; requires pairing with TDES4940RURR for complete link | Select only when building full V3Link chipset; not a drop-in replacement |
| SN65DSI86RKSR | MIPI DSI-to-eDP bridge; lacks V3Link interface, HDCP v1.4, and coax/STP support | Targets mobile SoC outputs (DSI), not V3Link video sources; no automotive temp rating | Consider only for DSI-based designs without V3Link infrastructure or HDCP requirements |
Compared with TSER953RURR (serializer-only) and SN65DSI86RKSR (DSI-based), the TDES4940RURR uniquely delivers V3Link deserialization, eDP v1.4b HBR3 output, integrated HDCP v1.4, and –20°C to +85°C operation - making it the sole fit for coax-based, secure, automotive-grade 4K display bridges.
