MIPI Alliance Releases A-PHY SerDes Interface for Automotive
The MIPI Alliance, an international organization that develops interface specifications for mobile and mobile-influenced industries, today announced the availability of MIPI A-PHY v1.0, the first industry-standard, long-reach serializer-deserializer (SerDes) physical layer interface. The new specification, available to MIPI members, provides an asymmetric data link in a point-to-point topology, providing high-speed unidirectional data, embedded bidirectional control data and optional power delivery over a single cable.
A-PHY v1.0 offers:
New solutions for in-car network connectivity
In conjunction with the availability of A-PHY v1.0, the Alliance today introduced MIPI Automotive SerDes Solutions (MASS). MASS will provide automotive OEMs and their suppliers with end-to-end high-performance connectivity solutions for the growing number of cameras, sensors and displays that enable automotive applications such as advanced driver-assistance systems (ADAS), connected in-vehicle infotainment (IVI) and, ultimately, fully autonomous vehicles. These solutions, with unprecedented functional safety and security built in at the protocol level, will help automakers integrate new and emerging safety features such as low-latency backup cameras, lane-keeping and sign-detection sensors and 360-degree camera, lidar and radar systems. MASS also will support multiple high-resolution instrumentation, control and entertainment displays.
"MIPI camera and display interfaces are already prevalent in vehicles today. MASS end-to-end solutions, with A-PHY as the cornerstone, will build on these mature specifications, leveraging economies of scale and providing the safety, security and reliability the auto industry requires," said Joel Huloux, chairman of MIPI Alliance. "Similar to how MIPI specifications are in billions of smartphones today, MASS will play a key role in designing the car of the future. These sets of specifications will deliver higher quality, lower cost, more choice and easier implementation for in-vehicle networks, benefiting the entire automotive supply chain."
MASS protocol stack
As the physical layer cornerstone, A-PHY's primary mission is to transfer high-speed data between cameras and displays and their related domain ECUs. Through the development of additional supporting specifications, MASS will allow proven higher-layer protocols from MIPI (such as MIPI CSI-2 and DSI-2) and third parties to operate over physical links spanning an entire vehicle, eliminating the need for proprietary "bridges" and PHYs. For OEMs and system integrators this equates to simplified networks and reduced costs, weight and development time.
With A-PHY as the physical layer, the MASS protocol stack consists of:
MIPI member companies participating in the A-PHY Subgroup include: Beijing ASL Technology Co., Ltd.; BitifEye Digital Test Solutions GmbH; Intel Corporation; Luxshare-ICT, Inc.; MediaTek Inc.; Mixel, Inc.; ON Semiconductor; Parade Technologies Ltd.; Primesoc Technologies; Prodigy Technovations Pvt. Ltd.; Qualcomm Incorporated; Robert Bosch GmbH; Sony Corporation; STMicroelectronics; Synopsys, Inc.; Tektronix, Inc.; Teledyne LeCroy; Toshiba Electronic Devices & Storage Corporation; Valens Semiconductor and others.
