DS90UB947TRGCTQ1

Overview

The DS90UB947TRGCTQ1 is a dual-lane FPD-Link III serializer manufactured by Texas Instruments, designed for automotive applications under AEC-Q100 Grade 2 qualification. It supports video resolutions up to WUXGA (1920x1200) and 1080p60 with 24-bit color depth at pixel clock frequencies up to 170 MHz. The device accepts OpenLDI input and converts it into dual differential FPD-Link III outputs. It operates within a temperature range of -40°C to +105°C TA and utilizes a 64-pin VQFN package. Power supply requirements include 1.8V and 3.3V rails.

Feature Summary

• Dual-lane FPD-Link III serialization for high-bandwidth video transmission
• OpenLDI receiver interface for direct display panel connectivity
• Supports up to 7.1 audio channels via I2S interface
• Backward compatible with DS90Ux926Q-Q1 and DS90Ux928-Q1 deserializers

Applications

• Automotive rear-view camera systems
• In-vehicle infotainment display interfaces
• Digital cockpit and instrument cluster connections

Procurement Notes

Verify the specific ordering suffix TRGCTQ1 to ensure the correct tape-and-reel packaging and automotive grade qualification. Confirm that the component matches the required AEC-Q100 standards for your target application environment. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit or obsolete stock issues during sourcing.

Selection Notes

Select this serializer when an OpenLDI source must be converted to a dual-lane FPD-Link III link. Ensure the downstream deserializer is compatible, such as the DS90UB948-Q1 or DS90UB940-Q1. Verify that the system cable length does not exceed the supported distance for single-ended coaxial or differential STP cables without signal integrity compromises.

Part Context

This component belongs to the DS90UB94x-Q1 family of serializers. It shares architectural similarities with the DS90UB949-Q1 but differs in input type, supporting OpenLDI instead of HDMI. It is part of the broader FPD-Link III ecosystem designed to reduce wiring complexity in automotive displays by integrating video, audio, and control data over minimal differential pairs.

Replacement Considerations

The DS90UB949TRGCTQ1 serves as a functional alternative if the input source is HDMI rather than OpenLDI. Both devices share similar output characteristics and backward compatibility with standard FPD-Link III deserializers. Verify pin-to-pin compatibility and register configuration differences before substitution.
