Valens announced that the MIPI Alliance has selected Valens technology as the foundation for the Alliance’s Automotive Physical Layer Standard (A-PHY). MIPI’s A-PHY standard will define an asymmetric physical layer for the automotive market to provide high-speed links for cameras, displays and sensors, through native CSI-2 and DSI/DSI-2 interfaces, for autonomous applications.
MIPI Alliance is a collaborative global organization serving industries that develop mobile and mobile-influenced devices. The focus of the organization is to design and promote hardware and software interfaces that simplify the integration of components built into a device, from the antenna and modem to peripherals and the application processor.
Valens’ technology provides the necessary resilience and performance for high-speed processing in the very noisy in-vehicle environment. It brings the most reliable and powerful solution to support high speeds required in connected and autonomous vehicles, over existing cables and connectors.
MIPI’s selection of Valens’ technology followed an in-depth evaluation process, including testing and analysis of several proposed solutions from MIPI’s member companies. Valens’ solution was determined best-suited to address the need for high-speed, in-vehicle video links, and to support the range of bandwidth defined by MIPI’s automotive standard.
MIPI outlined two main profiles for its A-PHY standard: Profile 1 to support lower speeds, and Profile 2 to support all speeds from 2 Gbps up to 48Gbps and above (e.g., 100 Gbps). Profile 2 will be based on a Valens’ PHY-level Retransmission Scheme (RTS) with Narrowband Interference Cancellation (NBIC), as published by the MIPI Alliance.
The final specification is expected to be completed by the end of 2019. MIPI’s will be the first high-speed asymmetric standard in the market.
