How to find the definition order of the CSI pins for Orin NX

I am designing the PCB board for the sensor and need the accurate definition and order of the CSI pins. This ensures that I can correctly connect it to the CSI interface of the Jetson Orin NX during the design process. How should I find the definition and order of the pins for this interface?

The key points are the corresponding pin order of MIPI Data and CLK, as well as the positions and order of PWDN and MCLK.

To find the definition and order of the CSI pins for the Jetson Orin NX, you should refer to the “Jetson Orin NX Series and Jetson Orin Nano Series Product Design Guide” (DG-10931-001_v1.4), specifically Chapter 10, “MIPI CSI Video Input”.

In this chapter, you will find Table 10-1, “Orin Module CSI Pin Descriptions”, which provides the detailed information you need. The table lists the pin number, module pin name, Orin signal, usage and description, recommended usage, direction, and pin type for each CSI pin.

Here is a summary of the CSI pin definitions and order:

  • CSI0_CLK_N (Pin 10) and CSI0_CLK_P (Pin 12) are the clock pins for CSI 0.
  • CSI0_D0_N (Pin 4) and CSI0_D0_P (Pin 6) are the data 0 pins for CSI 0.
  • CSI0_D1_N (Pin 16) and CSI0_D1_P (Pin 18) are the data 1 pins for CSI 0.
  • CSI1_CLK_N (Pin 9) and CSI1_CLK_P (Pin 11) are the clock pins for CSI 1.
  • CSI1_D0_N (Pin 3) and CSI1_D0_P (Pin 5) are the data 0 pins for CSI 1.

Make sure to note the recommended usage and direction for each pin to ensure correct connection to the CSI interface of the Jetson Orin NX.

Additionally, you should also refer to the “Orin Module Pin Mux” and “Orin (SoC) Technical Reference Manual (TRM)” for further information on configuring and using the CSI interface.

By following these guidelines, you should be able to accurately define and order the CSI pins for your PCB board design, ensuring correct connection to the Jetson Orin NX.

Refer to MIPI CSI Video Input chapter in the Jetson Orin NX Series and Orin Nano Series Design Guide https://developer.nvidia.com/downloads/jetson-orin-nx-series-nano-series-design-guide

Pin descriptions are in Table 10-1. Supported configuration options are in Table 10-3. Figure 10-1, Figure 10-2 provide useful information for 2 lane and 4 lane camera connection. Control signals in Figure 10-3.
