DS90UB984RURRQ1

Overview

The DS90UB984RURRQ1 is an automotive-grade FPD-Link IV to DisplayPort bridge deserializer. It supports VESA DP v1.4a/eDP v1.4b standards with HBR3 link rates up to 8.1Gbps per lane across 1, 2, or 4 lanes. The device features dual FPD-Link IV channels operating at speeds up to 27Gbps over coaxial or STP cables. It includes two fast-mode plus I2C interfaces (up to 1MHz) and high-speed GPIOs for SPI/UART pass-through. Powered by 1.8V and 1.15V supplies, it operates within a -40°C to +105°C range in an 88-pin VQFNP package.

• Supports VESA DP v1.4a/eDP v1.4b transmitter standards with HBR3/HBR2/HBR/RBR link bit rates
• Features selectable 1 or 2 channel FPD-Link IV interface with adaptive equalization
• Includes ultra-low latency control channel with dual I2C interfaces and high-speed GPIOs
• Provides backward compatibility with 720p and 1080p/2K FPD-Link III product families

Applications

• Central Information Displays (CID)
• Rear Seat Entertainment (RSE)
• Digital instrument clusters
• Head units and HMI modules
• Head Up Display (HUD)

Procurement Notes

Verify the specific ordering suffix against the latest TI Package Addendum to confirm moisture sensitivity level and reel specifications. Ensure compliance with AEC-Q100 Grade 2 requirements for your target temperature range. Confirm RoHS status and lead finish details directly from the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring conversion from FPD-Link IV serial links to local eDP displays. Verify that the host graphics processor supports the required DP lane count and AUX channel configurations. Ensure the system design accommodates the dual power supply rails and utilizes appropriate EMC controls like SSCG for automotive environments.

Part Context

This device belongs to the DS90Ux984-Q1 family of FPD-Link IV deserializers. It is designed to work in conjunction with FPD-Link IV serializers to transmit high-speed video and control data over low-cost interconnects. The series consolidates video, audio, and bidirectional control onto single cables to reduce system weight and complexity.
