摘要
针对数字音频广播单频网系统,结合ETSI国际标准的时间同步原理,提出一种基于FPGA并结合PCI总线架构的时间同步适配器设计方案。方案利用一片FPGA集成PCI总线传输控制、单频网适配、E1接口、GPS接口等模块,具有高通用性、可移植性和可升级性。采用Altera公司Cyclone I系列FPGA实现,占用逻辑单元3 150个,Fmax达到229.57 MHz。验证结果表明,本案正确可行。
This paper proposes a time-synchronized SFN（Single Frequency Network） Adapter of DAB（Digital Audio Broadcasting） system,which is designed based on the FPGA and associated with the PCI bus structure.This design improves the portability and upgrade performance of system by integrating all functions of the PCI controller,Adapter of SFN,E1 interface and GPS interface on one chip of FPGA.The FPGA of Cyclone from Altera used in this design occupies 3 150 LE.The Fmax is 229.57 MHz.The demonstration result shows that this design for solution is workable.
