Overview
The TDES4940RURT is a V3Link Enhanced Video to DisplayPort (DP) / Embedded DisplayPort (eDP) bridge deserializer manufactured by Texas Instruments. It supports VESA DP v1.4a/eDP v1.4b standards with HBR3/HBR2/HBR/RBR link bit rates up to 8.1Gbps per lane across 1, 2, or 4 lanes. The device receives high-speed serialized interfaces over coax or STP cables at data rates of 13.5/12.528/10.8/6.75/3.375 Gbps per channel, supporting up to 27 Gbps over dual channels. It handles 4K @ 60 Hz video resolution and integrates HDCP v1.4. Power supplies are 1.8V and 1.15V. Operating temperature ranges from -20°C to +85°C. It is housed in an 88-pin VQFNP package measuring 12 mm × 12 mm.
Feature Summary
- Supports V3Link Enhanced Video interface with selectable single or dual channel configurations for daisy-chain and splitting topologies.
- Integrates ultra-low latency control channel featuring fast-mode plus I2C and high-speed GPIOs supporting SPI and UART pass-through.
- Includes advanced image enhancement capabilities such as white balance and dithering alongside security features like unique ID for counterfeit protection.
- Provides advanced link robustness through spread spectrum clocking generation and adaptive receiver equalization.
Applications
- Operating room displays
- Seat back entertainment displays
- High resolution HMI
Procurement Notes
Verify the specific ordering suffix RURT indicates a small tape and reel quantity of 250 units compared to the RR variant which contains 2500 units. Confirm the package marking HR and moisture sensitivity level-3 rating align with your assembly process requirements. Ensure the NiPdAuAg lead finish matches your solderability specifications for the VQFN package.
Selection Notes
Select this component when interfacing V3Link Enhanced Video sources to standard DisplayPort or Embedded DisplayPort sinks. It is suitable for applications requiring consolidated video and control data transmission over low-cost interconnects. Consider the dual power supply requirement of 1.8V and 1.15V during system power architecture planning. Verify that the target display supports the required DP version and link configuration.
Part Context
This device belongs to the TDES4940 family of V3Link Enhanced Video deserializers. It functions as the receiver counterpart to V3Link Enhanced Video serializers, enabling high-bandwidth video transmission. The family supports various resolutions including 4K and 2K depending on the link mode and color depth configuration used in the system design.
