| PHY | Key Features | Typical Use | |------|----------------|----------------| | | 1-4 lanes, DDR clock, < 2.5 Gbps/lane, low pin count | CSI-2 (cameras), DSI (displays) | | M-PHY | Gear-based, embedded clock, high efficiency, up to 11.6 Gbps/lane | UFS, UniPro, PCIe over MIPI | | C-PHY | 3-wire/triad, embedded clock in transitions, > 2.5x D-PHY throughput | High-res displays, advanced cameras | | A-PHY | Long-reach (15m+), automotive-grade, high noise immunity | ADAS cameras, LiDAR, radar |
(Mobile Industry Processor Interface) is an acronym for the MIPI Alliance , a global organization that develops interface specifications for mobile and mobile-influenced devices. mipi standard
This is where the electrical engineering happens. CSI and DSI define the protocol (the language), but D-PHY and C-PHY define the physics (the voltage and signaling). | PHY | Key Features | Typical Use
The MIPI standard is the definition of "invisible infrastructure." It is not marketed on the side of a box, yet it is arguably the most critical enabler of modern consumer electronics. The MIPI standard is the definition of "invisible
In 2003, a consortium of leading technology companies, including ARM, Nokia, and Texas Instruments, came together to establish the MIPI Alliance. The primary goal was to develop a standardized interface specification that would facilitate the integration of mobile processors with various peripherals, such as cameras, displays, and storage devices.
