DS90UB901QSQX/NOPB

Overview

The DS90UB901QSQX/NOPB is a high-speed serializer manufactured by Texas Instruments, designed for automotive display applications. It converts parallel LVCMOS data into a serial LVDS output stream compliant with FPD-Link III standards. The device supports a maximum data rate of 688Mbps and features 14 parallel inputs and one differential LVDS output pair. It operates within a supply voltage range of 1.71V to 1.89V for the core and 3V to 3.6V for I/O. The component is housed in a 32-pin WQFN package measuring 5mm x 5mm with a height of 0.8mm. It is qualified to AEC-Q100 standards and functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Supports FPD-Link III standard for high-bandwidth video transmission
• Integrates 14-bit parallel LVCMOS input interface
• Includes integrated CDR for clock recovery from data stream
• Configurable via I2C interface for system integration

Applications

• Automotive camera systems
• In-vehicle infotainment displays
• Digital rear-view mirror systems
• ADAS sensor interfaces

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments; official documentation lists this part under Texas Instruments. Confirm the specific suffix 'SQX' indicates the tape and reel packaging variant distinct from other package options like 'SQE'. Ensure the datasheet version matches the production lot for accurate electrical specifications and pinout definitions.

Selection Notes

Select this component when a single-channel serializer is required for FPD-Link III links. It is suitable for replacing legacy serializers in automotive designs requiring AEC-Q100 qualification. Compare input counts against the source camera interface width to ensure compatibility. Verify that the board layout supports the 32-pin WQFN footprint and thermal requirements for the specified operating temperature range.

Part Context

This device belongs to the DS90UB901Q family of FPD-Link III serializers. It is functionally paired with deserializers such as the DS90UB913Q or DS90UB914Q to form complete video link solutions. The 'Q' suffix denotes automotive grade qualification, while 'NOPB' indicates lead-free and RoHS compliance. It serves as a critical interface between image sensors and processing units in modern vehicle architectures.

Replacement Considerations

Direct functional equivalents include the DS90UB901QSQE/NOPB and DS90UB901QSQ/NOPB, which share identical electrical characteristics but differ in packaging format. Cross-reference with the DS90UB902Q if additional channel capacity is needed. Verify pin-to-pin compatibility before substituting with non-TI components.
