Peripheral MIPIEdit

The MIPI interfaces available on iMX8MPlus SoC are following described:

  • The Camera Serial Interface (CSI) is a specification of the Mobile Industry Processor Interface (MIPI) Alliance. It defines an interface between a camera and a host processor.
  • The Display Serial Interface (DSI) is a specification by the Mobile Industry Processor Interface (MIPI) Alliance aimed at reducing the cost of display controllers in a mobile device. It is commonly targeted at LCD and similar display technologies.

The two CSI and the DSI interfaces on ORCA SOM are available on SODIMM connector.

DescriptionEdit

The MIPI CSI ports support the following standards and features:

  • MIPI D-PHY specification V1.2
  • Compliant to MIPI CSI2 Specification V1.3 except for C-PHY feature
  • Support primary and secondary Image format
    • YUV420, YUV420 (Legacy), YUV420 (CSPS), YUV422 of 8-bits and 10-bits
    • RGB565, RGB666, RGB888
    • RAW6, RAW7, RAW8, RAW10, RAW12, RAW14
    • All of User defined Byte-based Data packet
  • Support up to 4 lanes of D-PHY
  • Interfaces:
    • Compatible to PPI(Protocol-to-PHY Interface) in MIPI D-PHY Specification
    • AMBA3.0 APB Slave for Register configuration.
    • Image output data buswidth : 32 bits
  • Image memory:
    • Size of SRAM is 4KB
  • Pixel clock can be gated when no ppi data is coming.

The MIPI DSI port supports the following standards and features:

  • Complies to MIPI DSI Standard Specification V1.01r11
    • Maximum resolution ranges up to WQHD (1920x1080p60, 24bpp)
      • It should be decided on bandwidth between input clock (video clock) and output clock (D-PHY HS clock).
    • Supports 1, 2, 3, or 4 data lanes
    • Supports pixel format: 16bpp, 18bpp packed, 18bpp loosely packed (3 byte format), and 24bpp
  • Interfaces:
    • Complies with Protocol-to-PHY Interface (PPI) in 1.0Gbps / 1.5Gbps MIPI D-PHY
    • Supports RGB Interface for Video Image Input from general display controller
  • Supports S-i80(Synchronous i80) Interface for Command Mode Image input from display controller
  • Supports PMS control interface for PLL to configure byte clock frequency
  • Supports Prescaler to generate escape clock from byte clock

Pin mappingEdit

The Pin mapping is described in the Pinout table section
