时钟和时序

Renesas 的时钟发生器和合成器均是基于 PLL 的产品，因此可在一个应用中生成一个或多个时钟信号。 此类别包含的低抖动时钟发生器适用于高达 100G 的串行数据应用。PCIe 等其它许多应用将在应用特定型时钟部分进行单独讨论。 如果需要不止一个唯一的输出频率（如 100MHz 和 125MHz），可使用“输出库”参数选择器。 每个库与唯一的输出频率对应。 每个库的输出数量有很大差异，取决于时钟发生器。

一旦选定时钟发生器，可使用扇出缓冲器来提供额外的输出拷贝和类型（LVCMOS、LVPECL 等）。 Renesas 拥有业内最广泛的计时产品系列，适用于各种高度优化的解决方案。
