Firmenblog über Supply DS90UB941ASRTDTQ1: A High-Performance Serializer Designed for In-Vehicle Infotainment and ADAS Display Systems

As modern automobiles evolve toward “large screens” and “multi-screen integration,” engineers face the major challenge of achieving stable, long-distance transmission of high-resolution video signals within the complex electromagnetic environment of a vehicle. To address this need, Mingjiada Electronics maintains a long-term stock of the DS90UB941ASRTDTQ1. This device is a dual-channel DSI-to-FPD-Link III bridge serializer developed by TI (Texas Instruments), specifically designed for core applications such as In-Vehicle Infotainment (IVI), digital instrument clusters, and rear-seat entertainment systems.

Core Application Scenarios: Where is it primarily used?

This chip is primarily used in intelligent automotive cockpit systems to address the challenge of transmitting high-definition video from the processor to remote displays. Specific applications include:

In-Vehicle Infotainment (IVI) Systems: Supporting pixel clock speeds of up to 210 MHz, it can easily drive large central control screens with 3K (2880x1620), 2K, or 1080p60 resolutions, enabling smooth playback of navigation and video streams.

Multi-screen Interaction and Digital Instrument Clusters: Supports symmetric and asymmetric video splitting, allowing a single processor to simultaneously drive the instrument cluster (Cluster) and the central infotainment display (CID). It also transmits 8-channel I2S audio to ensure audio-video synchronization.

Rear Seat Entertainment (RSE) System: Utilizes the FPD-Link III interface to enable long-distance transmission via low-cost coaxial cable or shielded twisted pair (STP), simplifying wiring harness weight and enhancing system reliability.

Product Technical Analysis: Why Choose the DS90UB941ASRTDTQ1?

As an AEC-Q100 Grade 2 certified (-40°C to +105°C) automotive-grade chip, the DS90UB941ASRTDTQ1 offers significant performance advantages:

High-Bandwidth Input: Equipped with dual-port MIPI DSI interfaces, each channel supports data rates up to 1.5 Gbps, meeting the data throughput requirements of high-resolution displays.

Advanced EMI Suppression: Utilizes Low-Voltage Differential Signaling (LVDS) and data scrambling technology to effectively reduce electromagnetic interference even at high frequencies, which is critical for passing automotive-grade EMC testing.

Functional Safety-Ready: Provides supporting documentation to facilitate ISO 26262 functional safety system design, helping customers build automotive safety architectures compliant with ASIL levels.

Flexible Wiring Harness Compatibility: Supports 50Ω single-ended coaxial cable or 100Ω shielded twisted-pair (STP/STQ) cables, allowing engineers to choose flexibly based on cost and routing requirements.
