DS90UB988RURTQ1

Overview

The DS90UB988RURTQ1 is an automotive-grade FPD-Link IV to OpenLDI bridge deserializer. It supports dual-channel operation with per-channel rates up to 13.5Gbps, totaling 27Gbps over coax or STP/STQ cables. The device outputs a dual-pixel OpenLDI interface (10 LVDS data lanes + 2 clocks) supporting video up to 420MHz PCLK. It features configurable 18-bit, 24-bit, and 30-bit RGB streams, optional digital RGB parallel output up to 125MHz PCLK, and backward compatibility with FPD-Link III for 2K resolutions. Power supplies are 1.8V and 1.15V. It operates from -40°C to +105°C in an 88-pin VQFNP package.

Feature Summary

• Supports high-speed FPD-Link IV input with adaptive equalization and selectable channel configurations.
• Provides dual-port OpenLDI output compatible with existing LVDS-based displays and application processors.
• Includes ultra-low latency control channels with I2C and GPIO pass-through capabilities.
• Integrates security and diagnostics features such as link diagnostics, voltage/temperature monitoring, and unique ID authentication.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm packaging quantity and material specifications. Ensure that the selected variant matches the required moisture sensitivity level and peak reflow temperature ratings for the intended assembly process. Confirm availability status directly with authorized distributors as production statuses may change without notice.

Selection Notes

Select this component when bridging FPD-Link IV serializers to legacy LVDS/OpenLDI displays requiring high-resolution video support. Consider the backward compatibility mode if integration with FPD-Link III serializers is necessary for lower resolution applications. Evaluate the power supply requirements of 1.8V and 1.15V and ensure the PCB layout accommodates the 88-pin VQFNP package dimensions.

Part Context

This device belongs to the DS90UB988-Q1 family of automotive serializers and deserializers designed for high-bandwidth video transmission. It serves as a bridge between modern FPD-Link IV sources and traditional LVDS display interfaces, facilitating system upgrades without replacing existing display hardware. The Q1 designation indicates qualification for automotive environments under AEC-Q100 standards.
