Cypress EZ-USB FX3 SDK - CX3 MIPI CSI-2 interface

Cypress EZ-USB® FX3™ SDK Quick Start Guide, Version 1.3.1 45
The MIPI CSI-2 interface on the CX3 supports 1 to 4 CSI-2 data lanes and
RAW8/10/12/14, YUV422, and RGB888/666/565 image formats. It reads image
data from the sensor, de-packetizes it and sends it in to the parallel interface of the
fixed-function GPIF II interface on the CX3.
Support for the MIPI CSI-2 interface is provided through a new firmware library
added to the SDK (cyu3mipicsi.a). The APIs provided by the library and the data
structures and enumerations used by this interface are provided through the
cyu3mipicsi.h header file.
7.2 CX3 MIPI CSI-2 interface
7.2.1 Data Lanes
The MIPI CSI-2 interface on the CX3 supports 1 to 4 CSI-2 data lanes each
capable of transfers of up to 1 Gbps. The number of data lanes to be selected for a
CX3 application will depend upon the number of data lanes provided by the Image
Sensor and the total required data transfer rate.
7.2.2 MIPI CSI-2 stream formats supported by the CX3
The MIPI CSI-2 interface on the CX3 supports the following stream formats and
output modes:
