Switches to single-ended signaling with a higher voltage swing (1.2V) operating at much lower frequencies (typically under 10MHz). Control commands, initialization parameters, and sleep entry signals occur in LP mode.

The actual bitrate is 2.28 times the signal rate since seven C-PHY wire transitions correspond to 16 bits of data. C-PHY v1.2 goes up to 3.5 Gsymbols/s per trio; a typical application uses 3 trios, corresponding to ~24 Gbit/s total bandwidth. C-PHY v2.0 reaches up to 6 Gsymbols/s per trio.

For practical implementation without direct membership, hardware engineers frequently reference MIPI DSI implementation guides and datasheet appendices provided by microcontroller and Application Processor vendors (e.g., NXP, STMicroelectronics, Texas Instruments, or Qualcomm).

Key improvements in MIPI DSI-2 include:

The MIPI Display Serial Interface (DSI) is a high-speed, low-power interface specification designed for display applications in mobile and other devices. The MIPI DSI specification is widely adopted in the industry, enabling the connection of displays to host processors in a variety of applications, including smartphones, tablets, wearables, and automotive systems.
