DS90UB904QSQX/NOPB

Overview

The DS90UB904QSQX/NOPB is a display interface integrated circuit manufactured by Texas Instruments, functioning as an 18-bit color FPD-Link III deserializer. It supports data rates corresponding to frequencies between 10 MHz and 43 MHz. The device features a bidirectional control channel for system configuration and monitoring. It operates within a supply voltage range of 1.71 V to 1.89 V and is qualified under the AEC-Q100 standard for automotive applications. The component is housed in a WQFN-48 package and is designed for surface mount installation. It supports LVCMOS output types and includes I2C interface capabilities for configuration.

Feature Summary

• Supports 18-bit color video data transmission via FPD-Link III technology
• Includes a bidirectional control channel for enhanced system management
• Automotive grade qualification ensuring reliability in harsh environments

Applications

• Automotive camera systems requiring high-resolution video input
• In-vehicle infotainment displays utilizing FPD-Link III architecture
• Digital cockpit solutions needing robust display interface connectivity

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments; current documentation lists Texas Instruments as the producer. Confirm the specific suffix 'X' indicates the reel packaging variant if required for assembly processes. Ensure compatibility with the corresponding serializer component in the link topology. Check for moisture sensitivity level requirements during storage and handling procedures prior to soldering.

Selection Notes

Select this component when an 18-bit parallel LVCMOS output is required from a serial FPD-Link III source. Compare against the DS90UB902 series if only 14-bit resolution is sufficient for the application. Verify that the WQFN-48 footprint matches the PCB layout constraints. Ensure the power supply design accommodates the specified 1.71 V to 1.89 V operating range without exceeding the maximum limits.

Part Context

This part belongs to the DS90UB904Q family of FPD-Link III deserializers. It is functionally related to other members like the DS90UB904QSQ/NOPB, differing primarily in packaging or tape-and-reel specifications. The Q-suffix denotes automotive qualification, while the NOPB indicates lead-free construction. It serves as the receiver end of a point-to-point video link in automotive display architectures.

Replacement Considerations

The DS90UB904QSQ/NOPB is a direct functional equivalent within the same family, typically differing only in shipping packaging format. Verify pinout compatibility before substitution. Other variants in the DS90UB90x series may offer different bit depths or feature sets.
