直接数字频率合成器（DDS）需要一个基准本振（LO）来合成各种频率的波形。输出时钟在一定程度上继承了LO的频率稳定性。然而，非常稳定的时钟，如从原子标准产生的时钟，采用令人望而却步的价格作为LO。本文提出了一种利用白色兔子网络向多个从接收机分配频率参考的系统架构。该系统架构旨在成为一种具有竞争力的解决方案，以在大距离上分配频率参考。此外，不同的系统元素的非理想性，以及接收机频率损伤进行了研究，以评估其对分布式时钟的质量的影响。
Direct Digital frequency Synthesizers (DDS) require a reference local oscillator (LO) to synthesize waveforms with various frequencies. The output clock inherits to a certain degree the frequency stability of the LO. However, very stable clocks, as those generated from atomic standards, employ a prohibitive price to have as LO. In this paper, a system architecture that distributes a frequency reference to multiple slave receivers using the White Rabbit Network is presented. The system architecture aims to be a competitive solution to distribute frequency references over large distances. In addition, the non-ideality of the different system elements as well as the receiver frequency impairments are studied with the view to assess their influence on the quality of the distributed clock.
