Peripheral MIPI

The CSI-2 Host Controller is a digital core that implements all protocol functions defined in the MIPI CSI-2 Specification, providing an interface between the System and the MIPI D-PHY, allowing the communication with a MIPI CSI-2 compliant Camera Sensor

Description

The MIPI interface available on AXEL Lite is based on i.MX6 SoC and support the following features:

• Compliant with MIPI Alliance Standard for Camera Serial Interface 2 (CSI-2), Version 1.00 - 29 November 2005
• Interface with MIPI D-PHY following PHY Protocol Interface (PPI), as defined in MIPI Alliance Specification for D-PHY, Version 1.00.00 - 14 May 2009
• Supports up to 2 (S/DL) and 4 (D/Q) D-PHY Rx Data Lanes
• Dynamically configurable multi-lane merging
• Long and Short packet decoding
• Timing accurate signaling of Frame and Line synchronization packets
• Support for several frame formats such as:
  • General Frame or Digital Interlaced Video with or without accurate sync timing
  • Data type (Packet or Frame level) and Virtual Channel interleaving
• 32-bit Image Data Interface delivering data formatted as recommended in CSI-2 Specification
• Supports all primary and secondary data formats:
  • RGB, YUV and RAW color space definitions
  • From 24-bit down to 6-bit per pixel
  • Generic or user-defined byte-based data types
• Error detection and correction: PHY, Packet, Line, Frame

Camera ports

The MIPI CSI-2 Serial port supports the following standards and features:

i.MX 6Solo/6DualLite

• Supporting from 80 Mbps to 1 Gbps speed per data lane
• CSI-2 Receiver core can manage one clock lane and up to two lanes

i.MX 6Dual/6Quad

• Support up to 1Gbps per lane in 1/2/3-lane mode and up to 800 Mbps/lane in 4-lane mode
• CSI-2 Receiver core can manage one clock lane and up to four data lanes
