DS90UB903QSQE/NOPB

Overview

The DS90UB903QSQE/NOPB is an automotive-grade display interface integrated circuit from Texas Instruments, belonging to the FPD-Link III family. It functions as a serializer supporting 18-bit color depth with a maximum operating frequency of 43 MHz. The device operates within a supply voltage range of 1.71 V to 1.89 V and features CML output types. It is housed in a WQFN-40 package and complies with AEC-Q100 standards for operation between -40°C and +105°C.

Feature Summary

• Supports 18-bit color data transmission via FPD-Link III technology
• Includes a bidirectional control channel for I2C communication
• Certified for automotive applications under AEC-Q100 standards

Applications

• Automotive camera systems requiring high-resolution video input
• In-vehicle infotainment displays utilizing FPD-Link III architecture
• Digital cockpit interfaces demanding low-latency signal serialization

Procurement Notes

Verify the specific suffix 'E' against official documentation to confirm pinout or revision differences compared to standard variants. Ensure component authenticity through authorized channels due to automotive safety requirements. Confirm moisture sensitivity level handling procedures prior to surface mount assembly.

Selection Notes

Select this model when 18-bit color fidelity is required for upstream video sources. Compare against DS90UB902Q for 14-bit configurations if lower bandwidth suffices. Validate that the WQFN-40 footprint aligns with the target PCB layout constraints and thermal management strategy.

Part Context

This component extends the DS90UB90xQ series capabilities by increasing color depth support to 18 bits. It complements deserializers like the DS90UB960Q series within the FPD-Link III ecosystem. The device enables long-reach serial connections for automotive vision systems.

Replacement Considerations

DS90UB903QSQ/NOPB serves as the non-enhanced variant of this part number.
