Product details
Overview
DS90UB954TRGZRQ1 from Texas Instruments is an AEC-Q100 Grade 2 dual FPD-Link III deserializer hub that aggregates up to two 4.16 Gbps sensor streams and outputs MIPI CSI-2 compliant video at scalable lane rates (400–1600 Mbps/lane) with four virtual channels, ECC/CRC protection, and 2×2 output replication mode for automotive ADAS camera and RADAR systems.
For engineers reviewing the DS90UB954TRGZRQ1 datasheet, DS90UB954TRGZRQ1 pinout, DS90UB954TRGZRQ1 application, or DS90UB954TRGZRQ1 equivalent, this page delivers verified functional identity, validated pin roles, confirmed MIPI CSI-2 timing behavior, PoC-compatible coax/STP interface support, and real-world substitution guidance for rear-view, surround-view, and satellite RADAR sensor aggregation.
Technical Context
The DS90UB954TRGZRQ1 implements two independent FPD-Link III receive channels with adaptive equalization per channel, each supporting bidirectional control via low-latency BCC (I²C + GPIO forwarding), and integrates a dual-MIPI CSI-2 transmitter with programmable lane count (1–4), data rate (400/800/1500/1600 Mbps), and clock replication capability.
It operates across –40°C to +105°C ambient, supports Power-over-Coax (PoC) on 50-Ω coax or 100-Ω STP cabling, and features line fault detection, ISO 10605/IEC 61000-4-2 ESD compliance, and compatibility with DS90UB953-Q1, DS90UB935-Q1, DS90UB933-Q1, and DS90UB913A-Q1 serializers.

Key Features
| Feature | Design Value |
|---|---|
| 2×2 Output Replication Mode | Generates two identical MIPI CSI-2 streams (CLK0+D0–D3 and CLK1+D2–D3) for parallel processing and data logging without external duplication hardware |
| Adaptive Receive Equalization | Automatically compensates for cable loss up to 15 dB at 2.08 GHz - eliminates manual EQ tuning and maintains signal integrity across aging coax/STP |
| ECC & CRC Protection | End-to-end error detection on both FPD-Link III payload and CSI-2 transport - ensures reliable sensor data delivery in noisy automotive environments |
| Power-Over-Coax (PoC) Support | Enables single-cable solution for power, high-speed data, and bidirectional control - reduces harness weight and connector count in camera modules |
| Four Virtual Channels | Allows time-division multiplexing of multiple sensor sources (e.g., RGB + IR + depth) over one CSI-2 port - simplifies SoC interface resource allocation |
Applications
| Rear View Camera (RVC) | Surround View System (SVS) |
|---|---|
Use Scenario: Single-module aggregation of two rear-facing cameras (e.g., wide-angle + ultra-wide) into one MIPI CSI-2 interface for parking assist processing. IC Role / Device Role / Timing Role: Dual deserializer hub synchronizing and replicating video streams for display rendering and object detection pipelines. Use Value: Eliminates need for dual CSI-2 receivers on SoC; 2×2 replication enables simultaneous display output and AI inference with sub-frame latency. |
Use Scenario: Centralized hub receiving four camera feeds (front, rear, left, right) via two DS90UB954TRGZRQ1 devices, each aggregating two 2MP/60fps streams. IC Role / Device Role / Timing Role: High-bandwidth FPD-Link III deserializer with adaptive EQ ensuring robust signal recovery over long coax runs in vehicle body harnesses. Use Value: Maintains <2.7 ns UI jitter and <10 µs end-to-end latency - meets real-time stitching and motion compensation requirements. |
| Forward Vision Camera (FC) | Satellite RADAR Module |
Use Scenario: Aggregation of high-resolution forward-facing imager (e.g., 4MP/30fps) and companion IR sensor onto single CSI-2 port with virtual channel separation. IC Role / Device Role / Timing Role: MIPI CSI-2 transmitter with programmable lane count and data rate scaling - adapts to SoC CSI-2 receiver capabilities. Use Value: Supports 4-lane 1.6 Gbps operation for full bandwidth, or 2-lane 800 Mbps for power-constrained ECUs - no hardware redesign needed. |
Use Scenario: Interface between satellite RADAR transceiver (e.g., TI AWR2944) and central ADAS processor using FPD-Link III physical layer over coax. IC Role / Device Role / Timing Role: Deserializer with line fault detection and BCC-based diagnostic forwarding - monitors RADAR health and reports anomalies via I²C. Use Value: Enables fail-safe operation per ISO 26262 ASIL-B requirements through continuous link monitoring and ECC-protected data path. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar FPD-Link III deserializer hub applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90UB9702TRGCRQ1 | Single-input 6 Gbps FPD-Link IV deserializer with integrated serializer; no dual-hub or replication mode | Targeted at next-gen 8MP+ camera links; lacks 2×2 output replication and dual-Rx aggregation | Select when migrating to FPD-Link IV infrastructure and requiring higher per-port bandwidth, not dual-sensor aggregation |
| MAX96712GTJ/V+T | GMSL2 deserializer with 3 Gbps input, 4-lane MIPI CSI-2 output; no virtual channel support or PoC compatibility | Used in legacy GMSL2-based ADAS systems; requires separate GMSL2 serializer and different cabling architecture | Select only for GMSL2 ecosystem compatibility; not drop-in due to protocol, voltage, and diagnostic stack differences |
Compared with DS90UB954TRGZRQ1, DS90UB9702TRGCRQ1 offers higher per-channel bandwidth but removes dual-hub functionality essential for cost-sensitive 2-sensor modules, while MAX96712GTJ/V+T requires GMSL2-specific infrastructure and lacks the PoC integration and replication mode critical for automotive camera consolidation.

How does the 2×2 output replication mode function in DS90UB954TRGZRQ1?
In 2×2 replication mode, DS90UB954TRGZRQ1 generates two identical MIPI CSI-2 output streams: one on CSI_CLK0P/N with CSI_D0P/N–CSI_D3P/N, and a second on CSI_CLK1P/N with CSI_D2P/N–CSI_D3P/N. This enables simultaneous data logging and parallel processing without external hardware duplication - detailed in Section 3 (Description) and Figure 1-1 of SNLS570C.
