Product Overview
The RDK X5 GMSL Adapter Kit is a high-performance GMSL signal bridge solution developed in-house for machine vision perception. It fully supports the GMSL 1/2 protocol standards with per-channel link rates up to 6 Gbps and 3G/6G switching, and accepts four GMSL cameras simultaneously, aggregating them into the RDK X5 platform through dual MIPI CSI-2 interfaces — covering monocular, stereo, and multi-camera vision systems of every kind.
For synchronized triggering, two independent trigger channels output hardware sync signals from the RDK X5, distributing them simultaneously to the cameras and external sensor nodes such as LiDAR, with per-channel trigger LED indicators — providing a unified clock reference for multi-sensor timestamp alignment and hardware-synchronized capture.
For signal interconnect, the board implements physical-layer passthrough of IIC, GPIO, and UART, letting the host access remote camera register spaces and status pins directly. Paired with ALG Tech cameras, it can also carry CAN bus communication.
Aimed at machine vision integrators, research institutions, and independent developers, the kit wraps GMSL link configuration and low-level register tuning into standardized configuration steps — dramatically lowering the barrier to building high-bandwidth vision perception systems on the RDK X5 platform.
