摘要
在复杂的通信系统中,相同的设备往往需要根据实际情况进行不同速率的传输,设计出基于M-LVDS/RS485一种双速率通信系统。该通信系统核心板采用Alinx公司的ZYNQ系列的7035,M-LVDS采用TI公司的DS91M040接口芯片,RS485采用Maxim Integrated的ADM2565E接口芯片。该设计以FPGA为核心控制器,ARM9上进行数据处理,通过连接器实现M-LVDS的100 Mbps和RS485的20 Mbps双速率的数据传输,同时支持以太网口与上位机进行调试。
For complex communication systems,often the same equipment needs to be transmitted at different rates according to the actual situation,this paper designs a dual rate communication system based on M-LVDS/RS485.The core board of the communication system adopts the 7035 of the ZYNQ series of Alinx company,the M-LVDS adopts the DS91M040 interface chip of TI company,and the RS485 adopts the ADM2565E interface chip of Maxim Integrated.This design takes FPGA as the core controller,runs the operating system on ARM9,realizes the dual rate data transmission of 100 Mbps of M-LVDS and 20 Mbps of RS485 through connectors,and supports the communication between the Ethernet port and the upper computer.
