DS90UB904QSQ/NOPB

Overview

The DS90UB904QSQ/NOPB is an automotive-grade display interface integrated circuit manufactured by Texas Instruments, functioning as a FPD-Link III deserializer. It supports 18-bit color video data transmission with operating frequencies ranging from 10 MHz to 43 MHz. The device operates within a supply voltage range of 1.71 V to 1.89 V and features LVCMOS outputs. It is housed in a 48-pin WQFN package and is qualified under the AEC-Q100 standard for automotive applications. The component supports bidirectional control channels via I2C interfaces and functions reliably across an extended temperature range of -40°C to +105°C.

Feature Summary

• Supports high-speed 18-bit color video deserialization using the FPD-Link III protocol
• Enables bidirectional control communication through integrated I2C channels
• Designed for automotive environments with AEC-Q100 qualification

Applications

• Automotive camera systems requiring high-resolution video input
• In-vehicle infotainment displays connected to remote sensors
• Digital cockpit architectures utilizing multiple camera inputs

Procurement Notes

Verify the manufacturer designation carefully, as the model originates from National Semiconductor but is currently produced and distributed by Texas Instruments following their acquisition. Confirm that the specific suffix 'NOPB' indicates lead-free packaging and RoHS compliance before finalizing procurement orders to ensure alignment with environmental regulations.

Selection Notes

Select this component when an 18-bit parallel output interface is required for high-color-depth automotive displays. Ensure the design accommodates the 1.71 V to 1.89 V core voltage requirement. Compare against the DS90UB902QSQ/NOPB if only 14-bit resolution is sufficient, as it utilizes a smaller 40-pin package while maintaining similar automotive qualifications.

Part Context

This device belongs to the DS90UB904Q family of FPD-Link III deserializers. It serves as the receiver counterpart to serializers such as the DS90UR903 series. The Q-suffix denotes automotive grade qualification, distinguishing it from commercial variants. It is part of Texas Instruments' broader portfolio of display interface solutions designed for reliable vehicle networking.

Replacement Considerations

The DS90UB904QSQE/NOPB is a verified alternative variant within the same product line. Both devices share identical functional specifications and pinouts, differing primarily in manufacturing lot or minor process revisions. Verify package compatibility and electrical parameters before substituting.
