Mipi D-phy Specification V2.5 Pdf ⚡ [DELUXE]
A D-PHY lane shifts between states by altering the voltage levels of the two physical wires, DP (Data Plus) and DN (Data Negative). In LP mode, these wires are driven independently as LP-0 or LP-1.
The specification, released by the MIPI Alliance, defines a high-speed, low-power physical layer interface primarily used to connect peripherals (such as cameras and displays) to an application processor. While v1.x versions served the industry well for years, the v2.5 revision addresses the ballooning bandwidth requirements of modern mobile devices—specifically 4K/8K video streams and multi-camera sensor arrays—while maintaining the core philosophy of power efficiency.
Each lane contains two distinct types of line drivers and receivers operating over the same physical differential printed circuit board (PCB) traces:
If you are looking to design or implement this interface, it is highly recommended to obtain the official specification through the MIPI Alliance to ensure full compliance. mipi d-phy specification v2.5 pdf
To implement or verify a D-PHY v2.5 compliant interface, developers must adhere to strict electrical and timing parameters: High-Speed (HS) Mode Low-Power (LP) Mode Differential Single-Ended Logic High Level ( VOHcap V sub cap O cap H end-sub ) Max 360 mV 1.1 V to 1.3 V (1.2V Nominal) Logic Low Level ( VOLcap V sub cap O cap L end-sub ) -50 mV to 50 mV Differential Voltage ( VODcap V sub cap O cap D end-sub ) 140 mV – 270 mV Common Mode Voltage ( VCMcap V sub cap C cap M end-sub ) 150 mV – 250 mV Maximum Data Rate Up to 4.5 – 6.0 Gbps/lane Up to 10 Mbps
Version 2.5 reduces power consumption during low-power transitions through the Alternative Low-Power (ALP) state. ALP minimizes the traditional signaling overhead required when shifting between High-Speed and Low-Power modes, enabling faster wakeup times and lowering overall system power consumption. 4.
