Introduction to CoaXPress Protocol
- CoaXPress is a high-speed point-to-point serial standard that transmits image data, control signals, and power over a single coaxial cable, featuring low latency, high real-time performance, and strong anti-interference.
- Single-channel rate up to 12.5Gbps, 4-channel aggregation 50Gbps. Supports RG59/RG6 cables: 100m at 3.125Gbps, 35m at 12.5Gbps.
- Supports precise trigger via coaxial cable (no extra wiring). PoCXP integrates power, data, and control in one cable for simplified system design.
