More about MIPI A-PHY
MIPI A-PHY® is a long-reach serializer-deserializer (SerDes) physical layer interface for automotive applications, including ADAS, ADS and other surround-sensor applications, including cameras and in-vehicle infotainment (IVI) displays.
This specification reduces wiring, cost and weight, and allows designers to optimize systems for the performance, cost and complexity required by their use cases, providing scalability and flexibility to meet a broad range of speed and design needs.
It is anticipated that the first vehicles using A-PHY components will be in production in 2024.
In addition to automotive uses, the specification will be well-suited for applications such as IoT and industrial.
The MIPI A-PHY compliance program
The compliance program, which is being coordinated by BitifEye in partnership with Resillion, is now amid the first of four planned phases of development, which are expected to roll out over the next couple of years. The foundation of the program is the series of tests described in the draft A-PHY Reference Compliance Test Suite, which are being tested as part of the program's development.
The A-PHY Working Group’s focus areas for Phase I include formalization of TX testing, initial RX and protocol testing, and formalization of MOI documentation.
Ultimately, the compliance program will encompass full coverage of the A-PHY specification, with later phases extending to the many A-PHY protocol adaptation layer (PAL℠) specifications, which enable higher-layer protocols to operate seamlessly over the MIPI A-PHY physical link. PAL testing will likely begin with those for camera (MIPI CSI-2®) and then include others in the portfolio, such as those for I2C and GPIO.
Test event facilitated by Resillion
The MIPI A-PHY Compliance Program will hold its next test event at the Resillion laboratory in Hasselt, Belgium with testing taking place from 18 to 19 December. This will be the third event in the program to date. A first pilot-phase test event was completed in conjunction with MIPI’s Vancouver member meeting in October 2022, which was followed by a more extensive testing event hosted by Resillion (formerly Eurofins Digital Testing) that took place 11 May 2023.
