In high-speed imaging systems-especially in automotive and embedded environments-GMSL and MIPI CSI-2 are two common video transmission interfaces. Both serve to connect cameras to processors, but their design intent and use cases are fundamentally different.
GMSL vs MIPI: The Key Differences
| Feature | GMSL | MIPI CSI-2 |
|---|---|---|
| Purpose | Long-distance video transmission | Short-range sensor-to-SoC link |
| Distance | Up to 15–20 meters | Typically <30 cm |
| Cable Type | Coax or STP (e.g., GMSL cables) | PCB traces or FPC |
| Connectors | Fakra, H-MTD, mini-Fakra | Board-level interfaces |
| Signal Content | Video + Control + Power (PoC) | Video only |
| Common Use Cases | ADAS cameras, surround view, driver monitoring | Smartphones, tablets, in-cabin sensors |
In Short
- GMSL is ideal for long-range, high-speed video transmission in harsh environments such as vehicles.
- MIPI CSI-2 is used for short, board-level communication between image sensors and processors.
