DS90UB925QSQ/NOPB

Overview

The DS90UB925QSQ/NOPB is a serializer from the Texas Instruments DS90UB925Q series, designed for automotive applications. It converts 24 LVCMOS parallel inputs into a single FPD-Link III serial output with a data rate of 2.975 Gbps. The device operates within an ambient temperature range of -40°C to +105°C and requires dual power supplies: 1.71V to 1.89V for the core and 3V to 3.6V for I/O. It is housed in a 48-WQFN (7x7 mm) package with exposed pad, supports AEC-Q100 Grade 1 qualification, and features MSL level 3.

Feature Summary

• Supports high-speed serialization of 24-bit parallel video data via FPD-Link III interface
• Includes bidirectional control channel for register access and status monitoring
• Integrated clock recovery circuitry for reliable link synchronization
• Complies with automotive reliability standards including AEC-Q100

Applications

• Automotive surround view camera systems
• Digital cockpit display interfaces
• In-vehicle infotainment video transmission
• ADAS sensor data acquisition links

Procurement Notes

Verify the complete part number including suffixes such as NOPB against official Texas Instruments documentation to ensure correct packaging and material specifications. Confirm that the procurement source provides valid traceability records and authenticity guarantees, as counterfeit components may lack proper AEC-Q100 certification or exhibit incorrect electrical parameters.

Selection Notes

Select this component when a serializer is required to convert parallel LVCMOS video data to a single FPD-Link III lane. Ensure the system design accommodates the specific dual-voltage power requirements and the 48-pin WQFN thermal dissipation needs. Verify compatibility with downstream deserializers in the DS90UB9xx or DS90UH9xx families for proper link initialization and control channel operation.

Part Context

This device belongs to the DS90UB925Q family of FPD-Link III serializers. It is functionally paired with deserializers like the DS90UH926Q or DS90UB928Q to form complete video links. The 'Q' designation indicates automotive qualification, while 'SQE' specifies the specific tape-and-reel packaging variant offered by the manufacturer.

Replacement Considerations

Direct pin-to-pin replacements within the same FPD-Link III serializer family include the DS90UB925QSQX/NOPB. Other compatible serializers with different input counts, such as the DS90UB923Q or DS90UB927Q, require schematic redesign due to differing pin configurations and I/O counts.
