基于FPGA的音视频通用开发平台多时钟源设计

Design of the Multi-clock Source for a Audio/video Universal Hardware Platform Based on FPGA

讨论了构建FPGA音视频通用开发平台时需要提供多时钟的问题,分析比较了各种可能的解决方案。重点介绍和探讨了2款时钟发生器芯片,并给出了利用这2款芯片为FPGA音视频通用开发平台提供多个时钟的设计方案。最后讨论了时钟源设计时应注意的问题。

To construct a universal hardware platform for developing and testing audio/video processing system , multi-clock source is essential. In this paper multiple possible solutions to multi-clock source design are compared, a diagram of multi-clock source design using two programmable clock generators is proposed. The problems in the design are discussed and the suggestions to resolve them are given.
