DS90UB941ASRTDTQ1

Overview

The DS90UB941ASRTDTQ1 is an automotive-grade serializer from the DS90UB941AS series, designed to convert MIPI DSI video signals into FPD-Link III LVDS outputs. It supports dual MIPI DSI inputs and provides single or dual FPD-Link III output channels. The device accommodates resolutions up to 3K (2880x1620@30Hz) and operates with a pixel clock of up to 210 MHz. It features I2C and SPI control interfaces for configuration. The component is housed in a 64-pin VQFN package measuring 9x9 mm and is qualified under AEC-Q100 Grade 2 standards for operation within a temperature range of -40°C to +105°C.

Feature Summary

• Converts MIPI DSI input signals to FPD-Link III LVDS serial output
• Supports burst mode operation to reduce DSI interface power consumption
• Enables asymmetric separation using DSI Virtual Channel IDs
• Configurable port selection allows flexible mapping between DSI inputs and FPD-Link outputs

Applications

• Automotive display and infotainment systems requiring high-resolution video transmission
• Vehicle camera hub architectures utilizing FPD-Link III connectivity
• Applications necessitating low electromagnetic interference (EMI) design for in-car displays

Procurement Notes

Verify the complete part number including the RTDTQ1 suffix to ensure correct package type and automotive qualification level. Confirm that the specific revision matches the required AEC-Q100 Grade 2 certification. Check datasheet errata for any known silicon revisions affecting timing or register behavior before finalizing procurement specifications.

Selection Notes

Select this serializer when interfacing MIPI DSI sources with FPD-Link III deserializers such as the DS90UB948. Ensure the host processor supports the required DSI lane count and virtual channel configurations. Verify that the target display resolution and refresh rate fall within the supported 210 MHz pixel clock limit. Consider the available I2C/SPI control lines for system integration.

Part Context

This component belongs to the DS90UB941AS family of serializers. It serves as the counterpart to deserializers like the DS90UB948 in Texas Instruments' FPD-Link III ecosystem. The device is specifically engineered for automotive environments, offering robust signal integrity and diagnostic capabilities compared to non-automotive variants.

Replacement Considerations

The DS90UB941ASRTDRQ1 is a related variant within the same family. Verify if the Q1 suffix change implies different packaging or qualification requirements. No other direct pin-to-pin replacements are documented in the provided source material.
