AUSB3.0-based design of high-speed data channel for Charge Coupled Devices system

In order to solve the problem of high-speed data collection and transmission of CCD (Charge Coupled Devices) picture element, a USB 3.0 based design of high-speed data channel for CCD system is introduced in this paper. Through analyzing the requirement of the data throughput of a specific high-resolution and high frame rate CCD system, we propose this USB3.0-based scheme. By means of testing the actual speed of USB3.0 data channel, the proper USB-relevant parameters are obtained. The test indicates that the proposed USB-3.0-based design fulfills a maximal throughput of 224 Mbyte/s (1.79 Gbit/s) which makes it very suitable for high-speed CCD system. Furthermore, there is still enough throughput margin of the USB module, thus it is easily to be applied to where the higher-speed transmission is needed.
