Full Description

Scope

This A-PHY Specification document specifies the implementation of the A-PHY, including its layering, electrical characteristics, and its optional features.

Purpose

Long reach devices, and specifically automotive devices, face increasing bandwidth demands for each of their functions, as well as an increase in the number of functions integrated into the system. Addressing this demand requires wide bandwidth, low pin count (serial), highly power-efficient (network) interfaces with sufficient flexibility to be attractive for multiple applications, while employing just a single physical layer technology. A-PHY complements MIPI Alliance's existing D-PHY and C-PHY interfaces by addressing the long reach automotive channel.

Abstract

New IEEE Standard - Active. This standard adopts MIPI Alliance--MIPI A-PHY Specification Version 1.0 as an IEEE Standard. The adopted 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.
