何谓时钟同步器？
时钟同步器是构成世界通信基础设施系统的关键元件，包括基站、无线网络控制器、无线回程设备、路由器、网关、PON （无源光网络）、DSLAM （数字用户线接入多路复用器）、多业务交换平台和传输设备。 它们生成与所提供参考同步的相位、频率和时间输出。 通过确保输出上升沿与参考输入时钟上升沿的一致性，可实现相位同步。 通过确保输出频率与输入频率成比例一致，可实现频率同步。 时间同步确保输出有一个伴随信号，该信号将标识首次接收数据（与时钟一起传输）的时间。
如何选择时钟同步器：
瑞萨电子的同步解决方案充分利用多种技术，包括数字时钟合成器和模拟 PLL，有时会将它们整合到一个单芯片中。 数字合成器可确保达到标准要求，并能执行时钟监控、无中断参考切换和漂移过滤等功能；模拟 PLL 能转换频率和提供低抖动时钟。 ClockMatrix 系列设备是开始寻求同步解决方案的最佳场所。 如果您对更加基础的功能感兴趣，也可以考虑零延迟缓冲器。

IDT ClockMatrix™ Timing Solution for 100Gbps Interface Speeds (IEEE 1588, OTN, and SyncE)
Introducing the IDT ClockMatrix™ family of devices - high-performance, precision timing solutions designed to simplify clock designs for applications with up to 100 Gbps interface speeds.
They can be used anywhere in a system to perform critical timing functions, such as clock generation, frequency translation, jitter attenuation and phase alignment. A range of devices in the family support BBU, OTN, SyncE, synthesizer and jitter attenuator applications with several density options for each.
