基于TLK1501的高速数据收发电路设计

Design of TLK1501-based high-rate data transmitting/receiving circuits

为测量数据在光纤传输过程中的时延和误码率,设计了以光纤为传输介质的高速数据收发电路,采用TLK1501作为电信号到光信号的接口器件,利用FPGA(现场可编程门阵列)设计了接收端和发送端的单元电路,并对接收到的数据进行了比对,做误码分析。实验结果证明,该电路设计可靠性高,具有较高的实用性。

For measuring delay and BER in the process of data transmissions,this paper designs a high-rate data transceiver cir-cuit with fibers as the transmission media.Using TLK1501 as the interface device from electric signals to optical signals,it de-signs the unit circuit at the receiving and transmitting ends by using FPGA,compares the received data and conducts BER anal-ysis.The experimental results show that this circuit design is highly reliable and practical.
