JESD204B接口协议中的8B10B编码器设计

Implementation of 8B/10B Encoder Based on JESD204B Interface Protocol

基于JESD204B接口协议设计和实现了一种新型8B10B编码器。利用极性信息简化编码码表;利用3B4B与5B6B并行编码提升电路工作频率;利用人为加入一位均衡信息,减少逻辑处理层数。仿真结果表明,电路单元面积1 756 mm2、功耗1.13 m W及最大工作频率342 m Hz,相较于传统方法具有一定的改进且完全符合JESD204B协议规范。可应用于基于JESD204B接口协议的高速串行接口的设计中。

Designed and implemented an 8B/10B encoder based on the JESD204B protocol. Polarity information simplify the coding table. The parallel encoding of 3B4B and 5B6B improves the circuit operating frequency. The use of a balanced information reduces the logical processing layers.Simulation results show that the total cell area is 1 756 μm^2,power consumption is 1.13 mW and the maximum frequency is 342 MHz. Compared with the traditional methods it has some improvements and is fully compliant with JESD204B protocol specification, and it can be ap- plied to the design of high-speed serial interface based on the JESD204B interface protocol.
