摘要
在高动态条件下,高速串行数字信号的处理和传输,传统解决方案存在易失步、误码率高等方面的缺陷。近年来常用的并行同步解决方案也只是解决了整个传输系统的局部问题。本文结合新型高速光纤传输系统的研制,从物理层、链路层、数据层的角度出发,提出了数字化高速时钟恢复、并行比特同步、并行容错帧同步的组合设计方案,有效地减少了同步时间,提高了光纤系统数据传输效率,并成功应用于特种设备领域,取得了很好的效益。
The traditional methods dealing with high-speed and high-dynamic range signal suffer poor synchronization and high BER To solve these issues, this paper proposes three new methods that include digital CDR, parallel bit-synchronization and parallel error-tolerance frame-synchronization. A detailed presentation of the system is revealed. The testing results demonstrate that the system runs steadily and the synchronization recovery has been accomplished reliably.
