摘要
本文提出了一种新型的用于USB2.0高速模式下(480Mbps的数据传送率)的数据处理电路。这种电路采用八位并行的方法将数据转换为USB协议规定的数据格式,包含一个高速、低功耗的并串转换电路及一个八分频电路。芯片设计基于TSMC公司的0.25μmCMOS混合信号模型,采用半定制(semi-custom)的设计流程。电路的前后仿真结果表明该数据处理电路达到了480MHz的传输速度,符合USB2.0的要求。
A novel data processing circuit in high-speed serial communication has been demonstrated in this work. The circuit, including a serializer and a frequency divider, was developed to process the format of data transmission. The chip design is based on TSMC 0.25μm mixed signal model, and semi-custom design methodology was used. After pre- and post-layout simulation, results indicated that the speed of circuit has reached 480MHz. Moreover, the data are processed properly in agreement with USB2.0 specification.
