摘　　要：JESD204B协议规定的串行接口(Serdes接口)是ADC/DAC转换器与数字信号处理器之间进行数据传输和交换的新兴接口。对JESD204B接口协议规定的发送端电路进行了具体设计和实现。首先描述了协议对发送端电路的性能要求,然后给出了包含组帧器、控制器和数据链接层处理等三个主要电路模块的八通道发送端电路设计方案和具体实现过程。该设计还跟第三方IP核进行了对比仿真,结果表明,发送端电路能够完成协议规定功能,可直接应用于JESD204B协议规定的新兴接口电路设计。The serial interface（Serdes interface） provided by the JESD204 B protocol is a new interface for data transfer and exchange between ADC/DAC converter and digital signal processor. Sending circuit of JESD204 B interface agreement, has carried on the detailed design and implementation. First describes the performance requirements of the protocol for transmitter circuit. Then the design scheme and implementation process of the eight channel transmitter circuit are presented,which contains three main circuit modules, including group frame device, controller and data link layer processing.The design is compared with the third party IP core and the simulation results show that the sender can accurately complete the required functions which can be directly applied to the design of the new interface circuit provided by JESD204 B.
