TDES4940RURR

Overview

The TDES4940RURR 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, accommodating up to 8.1Gbps per lane across 1, 2, or 4 main lanes. The device handles 4K @ 60 Hz video resolutions and integrates HDCP v1.4 support. It operates on dual power supplies of 1.8V and 1.15V within an operating temperature range of -20°C to +85°C. Packaged in an 88-pin VQFNP (RUR) format measuring 12 mm x 12 mm, it features ultra-low latency control channels and advanced EMC controls.

Feature Summary

• Supports V3Link Enhanced Video interface with selectable single or dual channel configurations for high-speed serialized data transmission over coax or STP cables.
• Integrates VESA DP v1.4a/eDP v1.4b transmitter capabilities including HBR3 support and SuperFrame formats for high-resolution display applications.
• Includes built-in security features such as integrated HDCP v1.4 with on-chip keys and unique ID generation for counterfeit protection.
• Provides advanced link robustness through spread spectrum clocking generation (SSCG) and adaptive receiver equalization (AEQ).

Applications

• Operating room displays
• Seat back entertainment displays
• High resolution HMI

Procurement Notes

Verify the specific ordering suffix 'RURR' against the latest TI Package Option Addendum to confirm the 2500-unit large tape and reel packaging configuration. Ensure compatibility with the specified VQFNP 88-pin footprint and check moisture sensitivity level ratings prior to soldering. Confirm that the NiPdAuAg lead finish meets your assembly requirements.

Selection Notes

Select this component when designing systems requiring a bridge between V3Link Enhanced Video serializers and DP/eDP displays. Consider the dual-channel capability for bandwidth needs exceeding single-lane limits. Evaluate the thermal performance within the -20°C to +85°C range and ensure the 1.8V/1.15V power domains are correctly regulated for stable operation.

Part Context

This part belongs to the TDES4940 family of video bridge devices from Texas Instruments. It serves as the deserializer counterpart to V3Link Enhanced Video serializers, enabling consolidated video and control data transmission. The RURR suffix specifically denotes the reel packaging variant intended for automated surface-mount assembly processes.

Replacement Considerations

Consult the official TI product folder for direct equivalents. Verify pin-to-pin compatibility and electrical specifications if considering alternative bridge deserializers.
