Overview

The AD-GMSLCAMRPI-ADP# enables connecting GMSL serializer and deserialier Evaluation Kits (EVK) to a wide range of cameras and processing platforms supporting industry standard ribbon cable connectors. The adapter consists of three sections that can be broken apart from each other, with the following functionalities:

  • A Ribbon Cable Adapter having two pairs of 15-pin and 22-pin connectors routed to each other. The 15-pin connectors support 2 MIPI lanes, while the 22-pin connectors support 4 MIPI lanes.

  • A GMSL Serializer EVK Adapter with two 22-pin ribbon cable connectors, for connecting cameras to the GMSL serializers. A USB Type-A connector is available to supply 5V at 4A to another system.

  • A GMSL Deserializer EVK Adapter with two 22-pin ribbon cable connectors, for connecting to Raspberry Pi, Nvidia or Xilinx development platforms, or any other processing platform supporting the 15-pin or 22-pin ribbon cable connectors.

GMSL EV Kit Compatibility

The MIPI-CSI2 signals, I2C communication, and power pins align on the EV kits but the MFP connections can vary.

Refer to the Serializer and Deserializer EV Kit Compatibility Guide to see the connections across EV kits.

Camera Connections

Connect RPi 15-pin cameras to GMSL Serializer EV Kit’s with the 15-pin to 22-pin adapter. Or use a 15-pin to 22-Pin Adapter Cable.

SoC Connections

The same configuration is used for the SoC side where the 22-pin adapter can be directly connect to a Jetson Orin Development kit or use the 22-15 pin adapter to connect to an Raspberry Pi.
