MIPI D-PHY v2.5 (published 5 July 2019) is a maintenance release that refines the widely used D-PHY physical-layer specification for camera and display interfaces. It preserves backward compatibility while clarifying interoperability limits, adding channel and test guidance, and documenting optional features for longer links and optical transport.
The MIPI D-PHY v2.5 specification enhances mobile and IoT connectivity by offering data rates up to 4.5 Gbps per lane, extending reach with Alternative Low Power (ALP) mode to support longer, high-resolution display and camera cables . It serves as a, critical physical layer for automotive, IoT, and AR/VR applications by increasing data throughput to 24 Gbps in 4-lane configurations .

D-PHY v2.5 is designed to be backward compatible with previous versions. For example, a v2.5 transmitter can interoperate with earlier receivers, though maximum speeds may be limited by the older hardware (e.g., restricted to 1.5 Gbps without deskew or 2.5 Gbps with it when paired with v1.2 components).
