Область применения

The standard provides an asymmetric data link in a point-to-point or daisy-chain topology, with high-speed unidirectional data, embedded bidirectional control data and optional power delivery over a single cable. In this way, it reduces wiring, cost and weight, as high-speed data, control data and optional power share the same physical wiring. For integration with existing network backbones, it complements Ethernet, Controller Area Network (CAN), FlexRay and other interfaces.\nFeatures of A-PHY v1.0 include:\n•Ultra-low packet error rate (PER) of 10-19 over the vehicle lifetime\n•Ultra-high immunity to Electro Magnetic Compatibility (EMC) effects in demanding automotive conditions\n• A reach of up to 15 m\n• Data rate as high as 16 Gb/s with a roadmap to 48 Gb/s and beyond\nA-PHY v1.0 is available in two profiles and five gears to meet the various performance, cost and complexity requirements of different applications. It will also support coaxial cables and shielded differential pair (SDP) cables, each with up to four inline connectors.\nA-PHY also includes several functional safety provisions, such as cyclic redundancy checks (CRCs) in both the packet header and footer, an 8-bit message counter in the header to defend agains
