设计并实现了USB2.0安全设备控制器的物理层硬件模块。在此基础上,设计测试平台,搭建测试环境,对USB2.0物理层模块进行了全面的功能测试。实验结果表明,物理层模块能够配置在不同的工作模式下,并进行正确的数据发送与接收。
The circ ted in the paper. uit board of USB2.0 Physical Layer On the basis, testing platform and transceiver is designed and implemen testing USB2.0 Physical Layer transceiver is totally verified. Experimental the Physical Layer transceiver could be configured to work in diff results demonstrate and that erent operation mode to transmit and receive data properly.
