MIPI Protocol Adaptation Layer (PAL) specifications define the flows and mechanisms for various widely adopted higher-layer protocols to be carried across the MIPI A-PHY long-reach serializer-deserializer (SerDes) physical layer interface for automotive applications. MIPI PALs define the adaptations necessary to carry proven MIPI and approved third-party protocols over a MIPI A-PHY link to connect cameras and displays to their associated electronic control units (ECUs).
The MIPI PALs map those approved higher-layer protocols to MIPI A-PHY's A-Packet format, acting as a conduit to and from A-PHY’s generic data link layer. In this way, the PALs enable the higher-layer protocols to operate seamlessly over MIPI A-PHY physical links.
MIPI PALs are available to MIPI Alliance members. For information about becoming a member, see Join MIPI.
