新产品

  • AD9554- 四路PLL、四通道输入、八通道输出多服务线路卡自适应时钟转换器

    AD9554 是一款低环路带宽时钟转换器,可针对包括同步光纤网络(SONET/SDH)的许多系统提供抖动清除和同步功能。 AD9554产生的输出时钟可以与多达四路外部输入参考时钟同步。 数字PLL(DPLL)可以降低与外部参考时钟相关的输入时间抖动或相位噪声。 借助数字控制环路和保持电路,即使所有参考输入都失效,AD9554也能持续产生低抖动输出时钟。

    AD9554的工作温度范围为−40°C至+85°C工业温度范围。如果需要该器件的单或双DPLL版本,请分别参考AD9557或AD9559。

    应用

    • 网络同步,包括同步以太网和同步数字体系(SDH)至光纤传输网络(OTN)映射/解映射
    • 清除基准时钟抖动
    • 最高达到OC-192的SONET/SDH时钟,包括FEC
