1.5 MIPI CSI-2 Block
The CX3 device has an integrated MIPI CSI-2 block, which is hard-wired to the GPIF II interface on one side
and provides a MIPI CSI-2 interface on the other side to interface to an image sensor that supports MIPI CSI-
2. The block supports up to four MIPI CSI-2 data lanes, and is capable of speeds up to 1 Gbps per lane. The
MIPI CSI-2 receiver is connected to a fixed-function GPIF II controller via an 8-, 16-, or 24-bit data bus, which
can be clocked up to 100 MHz. The maximum bandwidth that can be achieved is 2.4Gbps (i.e. 24 * 100 Mbps).
The MIPI CSI-2 block is configured over I
2
C and is available on the CX3 I
2
C bus at the 7-bit I
2
C slave address
7’b0000111.
