Overview
The DS90UH925ATRHSTQ1 is a serializer from the Texas Instruments DS90UH925Q family, designed for FPD-Link III applications. It converts parallel LVCMOS video data into a serial LVDS output stream. The device supports pixel clock frequencies ranging from 5 MHz to 85 MHz and handles up to 24-bit color depth. It operates within an automotive temperature range of -40°C to +105°C and is qualified under AEC-Q100 standards. The component utilizes a WQFN-48 package for surface-mount installation.
Feature Summary
- Supports high-speed serialization of parallel RGB video data for automotive display systems
- Integrates HDCP functionality for secure content transmission
- Compatible with standard FPD-Link III deserializers for point-to-point connectivity
Applications
- Automotive rear-view camera systems
- In-cabin infotainment display interfaces
- Digital side mirror (eMirror) video links
Procurement Notes
Verify the specific suffix 'TRHST' against official datasheets to confirm tape-and-reel packaging and moisture sensitivity levels. Ensure the 'Q1' designation aligns with required automotive reliability standards for your target application environment before finalizing procurement.
Selection Notes
Select this component when a serializer supporting up to 85 MHz pixel clocks is required. It serves as a direct alternative to the DS90UB921 in designs where lower maximum frequency specifications are acceptable. Confirm compatibility with the paired deserializer, such as the DS90UB940, regarding GPIO pin sharing in 24-bit modes.
Part Context
This part belongs to the DS90UH925Q series of FPD-Link III serializers. It shares functional similarities with the DS90UB921 but offers a slightly different pixel clock range. The series is engineered for robust automotive video transmission with integrated security features.
Replacement Considerations
The DS90UB921 is a documented substitute within the same ecosystem. When replacing, configure the device for 18-bit mode if GPIO usage is required with certain deserializers like the DS90UB940.
