CSI Design Guidelines
CSI and DSI use the MIPI D-PHY for the physical interface. The routing and connection
requirements are found in the DSI section (Section 7.1),
Table 8-4.
MIPI CSI Signal Connections
Module Pin Name
CSI[4:0]_CLK_N/P
CSI[3:0]_D[1:0]_N/P
CSI4_D[3:0]_N/P
Note: Depending on the mechanical design of the platform and camera modules, ESD protection may be necessary. In addition, EMI
control may be needed. Both are shown in Figure 8-1. Any EMI/ESD solution must be compatible with the frequency required by the
design.

Description
CSI Differential Clocks. Connect to clock pins of camera. See Table 8-3
for details
CSI Differential Data Lanes: Connect to data pins of camera. See Table
8-3 for details
Description
Camera I2C Interface: Connect to I2C SCL and SDA
pins of imager. The CAM_I2C interface is connected
to the power monitor device on the module which
uses I2C address 7'h40.
Camera Master Clocks: Connect to camera reference
clock inputs.
Camera Power Control signals (or GPIOs [1:0]):
Connect to power down pins on camera(s).
