The MIPI D-PHY v2.5 specification defines a high-speed, low-power physical layer for mobile camera and display interfaces, focusing on enhanced data rates and power efficiency, according to the MIPI Alliance
To handle higher speeds without excessive heat or power draw, v2.5 incorporates sophisticated signaling techniques: Spread Spectrum Clocking (SSC): mipi d-phy specification v2.5 pdf
MIPI D-PHY (Digital PHY) is a physical layer specification developed by the Mobile Industry Processor Interface (MIPI) Alliance. It defines a high-speed, low-power interface for connecting peripherals, such as cameras, displays, and storage devices, to application processors in mobile and IoT devices. D-PHY uses a differential signaling scheme to transmit data over a pair of wires, allowing for high-speed data transfer while minimizing electromagnetic interference (EMI) and power consumption.

The MIPI D-PHY Specification v2.5 represents a significant maturation of the standard. While earlier versions (v1.0, v1.2, v2.0) laid the groundwork, v2.5 was released to keep pace with modern application processors and image sensors. What Changed in Version 2
