论文摘要
我们提出了一个具有快速重新同步功能和低延迟的行代码。编码器和解码器均已在FPGA中实现。编码器也已在ASIC中实现。整个光学链路的延迟（不包括光纤）估计小于73.9 ns。在辐射诱导的链路同步损耗的情况下，解码器可以恢复25 ns中的同步。线代码将用于ATLAS液体氩气量表I期触发升级，也可以在其他LHC实验中使用。
We propose a line code that has fast resynchronization capability and low latency. Both the encoder and decoder have been implemented in FPGAs. The encoder has also been implemented in an ASIC. The latency of the whole optical link (not including the optical fiber) is estimated to be less than 73.9 ns. In the case of radiation-induced link synchronization loss, the decoder can recover the synchronization in 25 ns. The line code will be used in the ATLAS liquid argon calorimeter Phase-I trigger upgrade and can also be potentially used in other LHC experiments.
