DS90UB903QSQ/NOPB

Overview

The DS90UB903QSQ/NOPB is a display interface integrated circuit manufactured by Texas Instruments, functioning as an 18-bit color FPD-Link III serializer. It supports data rates corresponding to frequencies between 10 MHz and 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 with SMD/SMT installation style. The component is qualified under AEC-Q100 standards for automotive applications, ensuring reliability across a wide operating temperature range from -40°C to +105°C.

Feature Summary

• Supports 18-bit color video transmission via the FPD-Link III protocol
• Includes a bidirectional control channel for I2C communication
• Qualified for automotive environments under AEC-Q100 standards

Applications

• Automotive camera systems requiring high-resolution video links
• In-vehicle infotainment display interfaces
• Advanced driver-assistance system (ADAS) sensor connections

Procurement Notes

Verify the manufacturer designation carefully, as the component is produced by Texas Instruments despite historical brand associations. Confirm the specific suffix NOPB indicates lead-free packaging compliant with RoHS directives. Ensure the WQFN-40 package variant matches the target PCB footprint requirements before ordering.

Selection Notes

Select this serializer when an 18-bit parallel input needs conversion to a single-lane FPD-Link III serial output. It is suitable for designs requiring bidirectional control capabilities alongside high-bandwidth video transmission. Verify that the system power supply can maintain the required 1.71 V to 1.89 V range for stable operation.

Part Context

This component belongs to the DS90UB903Q series of FPD-Link III serializers. It is part of a broader family of display interface ICs designed for automotive vision applications. The series typically pairs with compatible deserializers to form complete video link solutions for vehicle cameras and displays.

Replacement Considerations

Direct replacements within the same family include variants like DS90UB903QSQE/NOPB or DS90UB903QSQX/NOPB, which may differ only in packaging or tape-and-reel specifications. Cross-family alternatives require matching the FPD-Link III protocol and pinout compatibility.
