CSI-2 defines standard data transmission and control interfaces between transmitter and receiver.

• Data transmission interface (CSI-2)
• unidirectional differential serial interface with data and clock signals
• D-PHY for physical layer of CSI-2
• Control interface (CCI)
• bi-directional control interface compatible with I2C standard

• PHY layer (described in MIPI standard for D-PHY)
• Transmission medium
• Electrical parameters for signaling
• Timing relationship between clock and data lanes
• Protocol layer : The Protocol layer specifies how multiple data streams may be tagged and interleaved so each data stream can be properly reconstructed.
• Pixel/Byte packing/Unpacking layer : CSI-2 supports image applications with varying pixel formats from six to twenty-four bits per pixels. 8 bits per pixel data is transferred unchanged
• Transmitter : packs pixels from the Application layer into bytes before sending the data to the Low Level Protocol layer
• Receiver : unpacks bytes from the Low Level Protocol layer into pixels before sending the data to the Application layer
• Low level protocol : bit-level and byte-level synchronization for serial data transferred between SoT (Start of Transmission) and EoT (End of Transmission) events and for passing data to the next layer
• Transmitter : appends header and optional error-checking information on to data to be transmitted
• Receiver : header is stripped off and interpreted by corresponding logic in the receiver
• Lane management : CSI-2 is Lane-scalable for increased performance.
• Application layer : higher-level encoding and interpretation of data contained in the data stream. The CSI-2 specification describes the mapping of pixel values to bytes
