2. Introduction and Overview

2.1. Introduction

Thank you for purchasing a RAD-Phobos GMSL2 SerDes Media Converter from Intrepid Control Systems (ICS). This device serves as a repeater or splitter using GMSL2 SerDes technologies and features dual coax inputs and dual coax outputs.

2.2. Package Contents

Upon receipt, please remove, unwrap and inspect all its contents. If anything is missing or damaged, please contact Intrepid for prompt assistance using the Customer Support information at the end of this guide.

2.2.1. Hardware

Your media converter package includes the following:

  • SerDes Media Converter device

    pic1 pic2 pic3

  • 1x power cable

    pic4

  • 1x I2C breakout cable

    pic5


Optional Accessories

  • Standard FAKRA cable

    pic6

2.2.2. Software

Unless physical media was specifically requested, or your project is an engineering services project, there is no software associated with RAD-Phobos. The SerDes chip vendor Maxim GMSL from Analog Devices or Texas Instruments FPD-Link software can be used with RAD-Phobos by acquiring the proper 3.3v I2C communications device and connecting up to the external I2C connector on RAD-Phobos. Pinout details are on the back of the RAD-Phobos device.

You can contact Intrepid Controls Customer Support at: icssupport@intrepidcs.com.

Both software are available from the Maxim or TI portal websites, please speak to your local area representative to get an account.

Maxim software name is: Maxim Integrated GMSL SerDes GUI

Texas Instruments software name is: Texas Instruments - Analog LaunchPAD

Recommended Hardware for GMSL, works with Maxim software https://www.pjrc.com/store/teensy32.html

Recommended Hardware for FPD works ALPS TI tool https://www.ti.com/tool/USB2ANY

Additional Support for I2C communications will be provided by Intrepid Controls via a custom small from-factor pluggable (SFP) transceiver on the Rad-Gigastar product. This will allow seamless execution of I2C messages along with CAN and ethernet communications using Vehicle Spy3 Function blocks. The ability to simultaneously transmit and receive I2C messages using the same device brings value of having the Rad-Gigastar combined with RAD-Phobos.

3.4. Hardware Requirements

The SerDes media converter comes with a power supply adapter cable for this device. This device can be powered using an external DC supply. Ensure that the voltage is between 6V-40V and is rated for at least 1 Amps.

Power Consumption:
Power consumption will vary depending on how the unit is powered and what the unit is powering, typical power consumption is around 100mA at 13v with no cameras, at 13v each camera is around 200mA so the customer PoC circuit will need to supply a minimal of 500mA of steady state current.
Note: Power can be supplied in two ways:

  1. By external 2 pin to barrel jack connector

  2. Customer controller deserializer is able to supply power to RAD-Phobos, depending on the customer controller power circuit it should be able to power two cameras as well.

    Note: Port0 is the only port that will accept PoC power from the customer controller Deserializer, to power up either cameras and RAD-Phobos
