可编程时钟发生器（也被称为可编程计时装置）可帮助设计人员通过取代晶体、振荡器、可编程振荡器和含有单一计时装置的缓冲器的方式节省电路板空间和成本。 这使得它们极其适合于消费品、数据通信、电信和计算等应用。 这些器件通常被称为可编程时钟发生器或可编程 PLL 时钟发生器，或低功耗可编程时钟发生器。 在这些产品中，Renesas 的可编程时钟发生器系列包括第三代通用频率转换器 (UFT™)、FemtoClock® NG、MicroClock™、以及 VersaClock®，每种产品均提供不同级别的抖动性能、能耗、灵活性以及成本。

第三代通用频率转换器： 超高性能

UFT 系列可编程时钟发生器经过优化，适用于高性能光纤网络、无线基站和 100G 以太网 (GbE) 接口应用。 这些装置是业内首款单芯片可编程时钟发生器，能够在 12kHz 到 20MHz 的标准集成范围内生成 RMS 相位抖动低于 300 飞秒的八种不同输出频率。 可编程时钟发生器的第三代 UFT 系列提供了八种独立可编程时钟输出，并具有极大的灵活性，适用于几乎任何输入频率，并可选择几乎任何输出频率。

FemtoClock NG 和 VersaClock 6： 极高性能，低功耗

Renesas FemtoClock 新一代 (NG) 器件是独立的可编程时钟发生器/可编程振荡器，取代了高性能应用中的晶体和 SAW 振荡器。 这些可编程振荡器器件采用简单的低成本基频模式石英晶体作为低频参考，用来合成 RMS 相位抖动为 500fs、频率高达 1.3GHz 的高品质低抖动时钟信号。 VersaClock 6 具备与屡获殊荣的 VersaClock 5 系列产品相同的功能和灵活性，能够提供迄今为止最佳的性能。

VersaClock 3S： 极低功率，通用

VersaClock 3S 器件使得无需采用多个分离式计时组件，从而能够在节省板上空间的同时提供创新的节能功能。 VersaClock 3S 器件提供低功率和低抖动可扩展能力，满足包括 PCI Express® Gen 1/2/3 标准在内的各种广为采用的标准的要求，非常适合消费类、工业、计算以及汽车类应用。

MicroClock：超低功耗，微型封装

Renesas 的 MicroClock 系列超低功耗微型可编程时钟发生器，有助于最大限度地延长电池寿命，减小可穿戴设备、声频设备、智能设备和嵌入式系统的解决方案尺寸。每个器件包括三个输出、1 到 100MHz 的可选频率选项和可配置的扩展频谱时钟，旨在减少客户设计的 EMI。
