GMSL Cameras: High-Speed SerDes Solutions for ADAS & Autonomous Vision

GMSL (Gigabit Multimedia Serial Link) is a high-speed serial interface developed by Maxim Integrated (now Analog Devices). It is specifically designed to meet the rigorous demands of automotive, industrial, and medical imaging. GMSL technology enables the transmission of high-bandwidth video, audio, and bidirectional control signals over a single cable, making it the industry standard for next-generation vision systems.

Multi-Generation Compatibility

Our GMSL camera modules span three generations of evolution to fit various bandwidth and latency requirements:
• GMSL1: The foundation of high-speed serial links, providing reliable data transmission for entry-level ADAS.
• GMSL2: Offers significant bandwidth upgrades and is backward compatible with GMSL1, allowing for flexible transceiver matching and system scalability.
• GMSL3 (The New Standard): Delivering a massive 12 Gbps throughput, GMSL3 supports full MIPI CSI-2 / D-PHY v1.2 specifications. It enables uncompressed 4K resolution at 90 fps, ensuring ultra-smooth, real-time video streams for mission-critical applications.

Key Features & Advantages

1. Long-Distance, High-Integrity Transmission
GMSL cameras overcome the limitations of traditional parallel interfaces. By converting parallel data into high-frequency serial signals (SerDes), our cameras support:
• Up to 15 meters (or more) of stable transmission.
• Compatibility with 50Ω Coaxial or 100Ω Shielded Twisted Pair (STP) cables.
• Superior EMI/EMC performance for harsh electromagnetic environments.
2. Power over Coax (PoC) Integration
Simplify your system architecture with PoC technology. A single coaxial cable handles video data, control signals (I2C/UART), and power supply simultaneously. This reduces wiring weight, lowers installation costs, and improves overall system reliability.
3. Advanced Sensor Fusion & 3D Imaging
With GMSL3’s high-speed tunneling, our cameras are ideal for:
• Surround View Systems: Seamless 360° stitching with zero latency.
• Stereoscopic 3D Vision: Perfect synchronization for depth-sensing applications.
• Sensor Fusion: Aggregating data from multiple high-res sensors into a single SoC via a high-bandwidth link.

Primary Applications

• ADAS & Autonomous Driving: Forward-facing cameras for Lane Keep Assist (LKA) and Automatic Emergency Braking (AEB).
• In-Cabin Monitoring: High-frame-rate cameras for Driver Monitoring Systems (DMS) and Occupancy Monitoring (OMS).
• Industrial Automation: Long-range high-speed vision for robotics and automated guided vehicles (AGVs).
• Smart Infrastructure: Traffic monitoring and high-definition surveillance requiring long-distance cable runs.
