While MIPI D-PHY v2.5 remains a staple for modern camera and display architectures, the physical layer continues to evolve. The MIPI Alliance has subsequently introduced newer iterations, such as D-PHY v3.0, which doubles data rates even further, and the companion interface , which utilizes three-phase, 3-wire encoding to provide higher throughput without a dedicated clock. Nevertheless, understanding the foundational principles laid out in D-PHY v2.5 is the most critical step for any engineer mastering high-speed serial interface design.
