General description and application
SilkyEvCam USB consists of a PROPHESEE Event Based Vision Sensor (PPS3MVCD), a sensor board that outputs
MIPI signals from FPGA, and an interface board that converts MIPI signal to USB3.1 signal.
The Sync IN/OUT signals for synchronizing multiple SilkyEvCam are also interfaced with the IX connector.
This document describes SilkyEvCam product specifications.
Please refer to the information site provided by PROPHESEE for the specifications of the sensor(PPS3MVCD) andrelated applications.
See the CenturyArks website for the latest information.

7 Notes on Handling and Assembly
7.1.

Notes on Handling

When using this product, ensure safe design by heeding the following precautions.
1. Prevention of Electrostatic Discharge (ESD)
Event based sensors and other ICs can easily be damaged by static discharge. When handling these modules, takethe following measures to prevent static discharge.
(1) Either use non-chargeable gloves, clothes or material. Also use conductive shoes.
(2) Use a wrist strap when handling directly.
(3) Install grounded conductive mats on the floor and working table to prevent the generation of static electricity.
(4) Ionized air is recommended for discharge when handling Event based sensors.
(5) For the shipment of camera, use bag treated for the prevention of static charges.
2. Notes on storage and operating environments
Do not store or use the lens modules in harsh environments with high temperatures, high humidity levels, and highconcentrations of dust or in environments where condensation may form from moisture or dampness.
