扇出缓冲器 (时钟驱动器)

扇出缓冲器是许多时钟树的一个有用构建模块，可提供信号缓冲和输入信号的多个低偏斜拷贝。 单输入中的时钟缓冲器可减少前一驱动器上的负载，并提供有效的时钟分配网络。 单输出时钟缓冲器还用于将时钟从一个信号标准转化成另一个标准（例如，将 LVCMOS 输入转化成 LVPECL 输出）。 一些器件拥有集成式晶体振荡器，只需要低成本的外部基频模式石英晶体。 集成式振荡器提供极低的相位噪声参考时钟来驱动 PHY 时钟输入等抖动敏感型器件。 如果未在 Renesas 广泛的扇出缓冲器产品中找到确切的缓冲器配置，客户可考虑 Renesas 时钟分频器或时钟多录复用器产品组合中的器件，这些器件在“除 1”模式或适当选择的模式下使用时，也可用作扇出缓冲器。
