简介

该款全新的增强型“通用公共无线电接口(eCPRI)大规模多输入多输出(MIMO)远程无线电单元(RRU)”需要低相位噪声和杂散性能,以避免信道阻塞和干扰。 该系统要求时钟信号具有确定性延迟和低相位漂移,以确保接收器相位同步达到皮秒级。 这些元件构成了精确波束成形和 MIMO 架构的基础。 该设计经过优化,可实现高定时精度、集成度和灵活性,从而支持开发符合 5G 标准的网络和系统。

系统优势 :

  • 高度集成的定时源,无需额外的时钟器件
  • 支持同步以太网(SyncE)、JESD204B/C 和 IEEE 1588,满足 G.8262.1 和 G.8262 电信边界时钟要求以及 G.8273.2 C/D 类时间精度
  • 具有高性能毫米波宽带合成器,可产生高达 18GHz 的输出频率
