基于FPGA的ASI信号接收与发送的实现

The Implement of ASI Receiver and Transmitter Based on FPGA

提出了一种用FPGA芯片代替Cypress公司的CY78933和CY78923芯片来实现ASI信号接收与发送的方案,详细阐述了DVB-ASI接口的硬件组成与FPGA实现,该接口符合DVB-ASI的接口规范,可实现270 Mbps的信号传输,已经得到实际运用。

This paper presents a scheme to implement ASI receiver and transmitter based on FPGA to replace the scheme based on CY7B933 and CY7B923 of Cypress. The hardware design and the design about FPGA of the ASI interface are described in detail. This scheme works with 270 megabits per second （Mbps） DVB - ASI, as defined by the DVB-ASI specification and gained application in practice.
