DS90UH925QSQ/NOPB

Overview

The DS90UH925QSQ/NOPB is a serializer within the FPD-Link III family, designed for automotive applications under AEC-Q100 qualification. It converts parallel LVCMOS video data into a high-speed serial output stream with a maximum data rate of 2.975 Gb/s. The device accepts up to 31 inputs and operates on a single 3.3 V power supply. It supports pixel clock frequencies ranging from 5 MHz to 85 MHz and functions reliably across an extended temperature range of -40°C to +105°C. The component is housed in a compact 48-WQFN package.

Feature Summary

• Supports FPD-Link III protocol for high-bandwidth video transmission
• Integrates internal test pattern generation for system validation
• Provides bidirectional control channel for register access and GPIO
• Features low jitter architecture for stable signal integrity

Applications

• Automotive surround view camera systems
• Digital cockpit display interfaces
• Advanced driver assistance system (ADAS) sensor links

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with the paired deserializer regarding pixel clock frequency ranges and configuration modes. Confirm that the ordering part number matches the required RoHS compliance status and moisture sensitivity level for your assembly process.

Selection Notes

Select this serializer when interfacing with FPD-Link III compatible deserializers such as the DS90UB940. Ensure the source camera interface voltage aligns with the device's 3.3 V requirement. Verify that the application's pixel clock falls within the supported 5 MHz to 85 MHz range. Consider the 48-pin WQFN footprint constraints during PCB layout planning.

Part Context

This component belongs to the DS90UH92xQ series of FPD-Link III serializers. It serves as the transmitter side of the link, converting parallel RGB or YUV data streams into serialized differential signals. It is engineered to replace older legacy serializers while offering improved bandwidth and integrated diagnostic features for modern automotive vision systems.

Replacement Considerations

The DS90UH927QSQ/NOPB is a documented alternative within the same family. Note that pairing with certain deserializers may require specific configuration adjustments, such as operating in 18-bit mode to utilize GPIO pins.
