时钟和时序

Renesas 时钟缓冲器（时钟驱动器）产品组合包括带有多达 27 个输出端的器件。如 LVPECL、LVDS、HCSL、CML、HSTL 和可选输出等差分输出，都支持高达 3.2GHz 的输出频率和频率高达 350MHz 的单端 LVCMOS 输出。 部分缓冲器带混合输出信号。 Renesas 的多路复用器产品组合中有一些器件支持 1.2V 至 5V 电源电压，可在商业和工业温度范围内使用。 扇出缓冲器和时钟分频器是可用于多种应用的通用时钟构建模块器件。 对于包括个人电脑、消费类电子产品或工业系统，以及高性能网络和通信系统在内的各种系统而言，它们都是分配时钟和信号的理想选择。

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。
