DS90UB984RURTQ1

Overview

The DS90UB984RURTQ1 is an automotive-grade FPD-Link IV to Embedded DisplayPort (eDP) bridge deserializer manufactured by Texas Instruments. It operates within a temperature range of -40°C to +105°C and utilizes a VQFNP-88 package measuring 12mm x 12mm. The device supports dual-channel FPD-Link IV input with per-channel rates up to 13.5Gbps, totaling 27Gbps. It features a DisplayPort transmitter compliant with VESA DP v1.4a/eDP v1.4b standards, supporting HBR3 link bit rates at up to 8.1Gbps per lane across one, two, or four lanes. Power requirements include 1.8V and 1.15V dual supplies.

Feature Summary

• Supports 4K video resolution extraction to local eDP displays with stream synchronization capabilities
• Provides ultra-low latency control channels with high-speed GPIO pass-through for SPI and UART
• Integrates security and diagnostics including voltage/temperature monitoring, BIST, and unique ID authentication
• Ensures advanced link robustness through adaptive equalization and spread spectrum clocking generation

Applications

• Central Information Displays (CID)
• Digital instrument clusters
• Head Up Displays (HUD)
• Rear view and side mirror displays

Procurement Notes

Verify the specific ordering suffix 'T' indicates the small tape-and-reel carrier configuration containing 250 units. Confirm that the component meets AEC-Q100 Grade 2 qualification standards required for your target automotive environment. Ensure design compatibility with the specified 1.8V and 1.15V dual power supply rails during the schematic capture phase.

Selection Notes

Select this component when interfacing FPD-Link IV serializers to local embedded DisplayPort panels in automotive settings. It is suitable for designs requiring backward compatibility with FPD-Link III resolutions up to 2K. Consider the VQFNP-88 footprint constraints and thermal dissipation requirements associated with the 12mm x 12mm package dimensions.

Part Context

This part belongs to the DS90UB984-Q1 series of bridge deserializers designed for automotive display architectures. It functions as the endpoint receiver for high-speed serialized video links, converting them into standard DisplayPort signals for direct panel connection. The series emphasizes reduced interconnect weight and simplified system design through consolidated data transmission over coaxial or STP cables.

Replacement Considerations

DS90UB984RURRQ1 serves as a functional equivalent offering identical electrical specifications but packaged in a large tape-and-reel format containing 2500 units.
