DS90UB901QSQE/NOPB

Overview

The DS90UB901QSQE/NOPB is a single-channel LVDS serializer designed for automotive display applications, certified to AEC-Q100 standards. It converts parallel LVCMOS inputs into a high-speed serial LVDS output stream operating at a maximum data rate of 688Mbps. The device supports up to 14-bit color depth and features a bidirectional control channel for configuration and status monitoring via I2C. It operates within a supply voltage range of 1.71V to 1.89V and functions reliably across an extended temperature range from -40°C to +105°C. The component is housed in a compact 32-pin WQFN package measuring 5mm x 5mm with a height of 0.8mm.

Feature Summary

• Supports FPD-Link III interface protocol for high-bandwidth video transmission
• Integrates a bidirectional control channel for system configuration and diagnostics
• Converts parallel LVCMOS signals to differential LVDS for noise-immune transmission

Applications

• Automotive rear-view camera systems
• In-vehicle infotainment display interfaces
• Digital cockpit and instrument cluster connections

Procurement Notes

Verify the complete part number including the suffix 'E' against official Texas Instruments documentation to ensure correct packaging and material specifications. Confirm that the AEC-Q100 qualification grade matches the specific reliability requirements of the target automotive application before finalizing procurement.

Selection Notes

Select this component when a single-channel serializer is required for FPD-Link III architectures. Ensure the design accommodates the 32-pin WQFN footprint and the specific 1.71V to 1.89V power supply constraints. Verify compatibility with the corresponding deserializer, such as the DS90UB902, for the complete link solution.

Part Context

This device belongs to the DS90UB901Q family of FPD-Link III serializers. It is engineered specifically for automotive environments, offering robust signal integrity over long cable runs. The Q-suffix indicates automotive-grade qualification, distinguishing it from standard commercial variants while maintaining pin-to-pin compatibility within the series.

Replacement Considerations

The DS90UB901QSQ/NOPB serves as a direct functional substitute, differing primarily in packaging style rather than electrical performance. Verify that any alternative component maintains identical FPD-Link III protocol support and AEC-Q100 certification for automotive use.
