Deliver a stable 1080p camera signal over 15–20 meters in a noisy automotive environment.
Achieve glass-to-glass latency well under 100 ms for real-time driver visibility.
Ensure rugged hardware, seamless Linux BSP/V4L2 support, and PoC-based power delivery.
Legacy truck rear-view camera systems failed to handle long-distance footage, low-latency, and severe situations. The customer sought a dependable solution. Power supply and Linux BSP integration complicated things.
MIPI CSI-2 is meant for <30 cm runs, so sending it 15–20 m in a noisy truck environment risks severe signal integrity issues.
Safety-critical reversing operations demanded sub-100 ms glass-to-glass latency.
Equipment needed to endure vibration, temperature extremes, moisture, and dirt.
Supplying power to the camera over long distances without voltage drop or noise.
Camera system needed full V4L2/Media Controller integration within the custom Yocto-based BSP.
Silicon Signals designed and delivered a GMSL-based SerDes link architecture to meet all performance and reliability requirements
OV2311 image sensor + GMSL serializer converts MIPI CSI-2 into high-speed serial video stream.
Automotive-grade coax/STP carries video, I²C control, GPIOs, and power over PoC in a single link.
NXP i.MX8QXP ECU with GMSL deserializer linked to CSI-2 receiver, featuring integrated PoC circuit.
Custom Linux V4L2 sub-device driver handles GMSL link init, PoC management, and error reporting.
Standard V4L2 sensor driver routed via GMSL’s virtual I²C bridge ensures reliable image streaming.
Optimized GStreamer userspace display with kmssink enables ultra-low latency video performance.
Proven Engineering Outcomes That Delivered Our Client Low-Latency Video, Rugged Design, and Automotive Reliability.
