DS90UB988RURRQ1

Overview

The DS90UB988RURRQ1 is an automotive-grade FPD-Link IV to OpenLDI bridge deserializer manufactured by Texas Instruments. It operates within a -40°C to +105°C temperature range and utilizes a VQFNP package with 88 pins 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 two OpenLDI outputs supporting clock frequencies from 8MHz to 210MHz per port, accommodating video resolutions up to 4K (30-bit color depth). Power requirements include 1.8V and 1.15V supplies.

Feature Summary

• Supports high-speed serial transmission over coaxial or STP cables using FPD-Link IV technology
• Provides dual-port OpenLDI output for connecting to existing LVDS-based displays
• Integrates ultra-low latency control channels with I2C and GPIO pass-through capabilities
• Includes advanced diagnostic features such as link diagnostics, voltage/temperature monitoring, and BIST

Applications

• Central Information Displays (CID)
• Digital instrument clusters
• Head Up Display (HUD)
• Rear Seat Entertainment (RSE) systems
• Side mirror displays

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm packaging quantity and moisture sensitivity level. Ensure that the procurement channel provides valid traceability documentation required for automotive components. Confirm RoHS compliance status and lead finish specifications prior to placing orders to match assembly process requirements.

Selection Notes

Select this component when interfacing FPD-Link IV serializers with legacy LVDS/OpenLDI displays in automotive environments. Verify that the system requires dual-pixel link support and backward compatibility with FPD-Link III modes if necessary. Ensure power supply rails of 1.8V and 1.15V are available and that the PCB layout accommodates the 88-pin VQFNP package dimensions.

Part Context

This device belongs to the DS90UB988-Q1 family of FPD-Link IV deserializers designed for automotive applications. It complements serializers like the DS90UH988 series to form complete bridge solutions. The Q1 suffix indicates AEC-Q100 Grade 2 qualification, ensuring reliability under harsh automotive operating conditions compared to non-automotive variants.

Replacement Considerations

Direct replacements within the same family include the DS90UB988RURTQ1, which shares identical electrical characteristics but differs in tape and reel packaging quantity.
