摘要
前端调制器是HFC网络实现数据传输的关键设备,从DVB-C标准入手,给出前端调制器组成框图,对系统的BCM3033芯片和FPGA等主要组成模块进行分析与讨论,给出设计方案,最后给出调制器性能的实测结果。
The Head-end modulator is the key equipment for data transmission applied in HFC network. This paper introduces DVB - C standard. Then it puts forward the conceptual block diagram of head-end modulator and analyzed the main modules of the modulator. These modules include the BCM3033 chip and Flea modules. At last, this paper presents the measuring results of modulator.
