Thank you! MIPI Protocol Introduction MIPI Development Team  2010-9-2 What is MIPI? MIPI stands for Mobile Industry Processor Interface MIPI Alliance is a collaboration of mobile industry leaders. Objective to promote open standards for interfaces to mobile application processors. Intends to speed deployment of new services to mobile users by establishing Spec. Board Members in MIPI Alliance Intel, Motorola, Nokia, NXP,Samsung, ST, TI What is MIPI? MIPI Alliance Specification for display DCS (Display Command Set) DCS is a standardized command set intended for command mode display modules. DBI, DPI (Display Bus Interface, Display Pixel Interface) DBI：Parallel interfaces to display modules having display controllers and frame buffers. DPI：Parallel interfaces to display modules without on-panel display controller or frame buffer. DSI, CSI (Display Serial Interface, Camera Serial Interface) DSI specifies a high-speed serial interface between a host processor and display module. CSI specifies a high-speed serial interface between a host processor and camera module. D-PHY D-PHY provides the physical layer definition for DSI and CSI. DSI Layers DCS spec DSI spec D-PHY spec Outline D-PHY Introduction Lane Module, State and Line levels Operating Modes Escape Mode System Power States Electrical Characteristics Summary Introduction for D-PHY D-PHY describes a source synchronous, high speed, low power, low cost PHY A PHY configuration contains A Clock Lane One or more Data Lanes Three main lane types Unidirectional Clock Lane Unidirectional Data Lane Bi-directional Data Lane Transmission Mode Low-Power signaling mode for control purpose：10MHz (max) High-Speed signaling mode for fast-data traffic：80Mbps ~ 1Gbps per Lane D-PHY low-level protocol specifies a minimum data unit of one byte A transmitter shall send data LSB first, MSB last.
