Offering a significant improvement in speed over CoaXPress v 1.1, CoaXPress 2.0 extends the data transfer rate up to 12.5 Gbps for cables lengths of up to 40m, and up to 40 Mbps for bidirectional communications. It supports higher frame rates or higher camera resolutions for developing even higher-performance video imaging systems. Key advantages of this new version of the standard include:
Microchips CoaXPress 2.0 family of devices has been designed in conjunction with the development of the CoaXPress 2.0 specification. These devices deliver unprecedented speed, performance and flexibility to help you keep pace with leading-edge industrial, embedded and machine vision application requirements. A true all-in-one solution, these devices incorporate an integrated equalizer, a cable driver plus these two unique features, which enable camera and capture card manufacturers to relax their design tolerances:
Bit Rate (Gbps) | Typical Maximum Cable Length (m) |
1.25 | 130 |
2.5 | 110 |
3.125 | 100 |
5 | 65 |
6.25 | 55 |
10 | 40 |

Microchip collaborated with industry partners to provide a complete connectivity solution that leverages the benefits of CoaXPress technology for developing autonomous driving and ADAS applications. The diagram below demonstrates how to implement two MIPI CSI-2 to CoaXPress bridges for a camera sensor node and an Engine Control Unit (ECU) node. This solution transports aggregated sensor data from two 8-megapixel image sensors while also providing a simultaneous 40 Mbps uplink for control and power over a single automotive coaxial cable with four inline connectors.
