Adoption of the MIPI A-PHY Specification Version 1.1

This A-PHY Specification document specifies the implementation of the A-PHY, including its layering, electrical characteristics, and optional features. Different protocols employing A-PHY technology can have different constraints, which can require the use of different approaches for operation control. Therefore, while this document provides the features to enable stable, optimized Link configuration, it does not mandate specific configurations for specific channels.

IEEE Standard for Adoption of MIPI Alliance Specification for A-PHY Interface (A-PHY) Version 1.0

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.

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.

No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.

No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.

No Inactive-Reserved Standards
