Clocks

Analog Devices offers ultralow jitter clock generation, distribution, and synchronization products for various applications. ADI clock products are ideal for clocking high performance analog-to-digital converters (ADCs), digital-to-analog converters (DACs), or peripheral digital devices. ADI clock ICs integrate PLL cores, dividers, phase offset, skew adjust, clock drivers, time-to-digital converters, and other features in small chip scale packages.

Pulse & PWM Generators

Analog Devices’ programmable pulse-width modulators (PWM) and pulse generators offer the ability to easily control output duty cycle with a single input voltage. Offering duty cycles from 0% to 100% and a wide range of adjustable output frequencies, these small low power devices are ideal for simplifying applications including light dimming, isolated proportional control, efficient load control, and more.

时钟和数据恢复/重定时

ADI公司提供面向设备设计的分立式速率、多速率和连续调谐时钟和数据恢复IC，包括城域网络、远程、DWDM和FSO应用。ADI CDR可轻松集成到与协议无关的应用中，无需借助参考时钟，也可自动锁定12.3 Mbps至2.7 Gbps范围内的任意速率输入数据流，同时还能通过I2C接口报告获得的数据速率。

实时时钟

实时时钟(RTC) IC用在电路中，用于跟踪与“真实”世界相关的时间。保持准确的时间非常重要，尤其是在系统承受很大压力，或者主设备电源关断时。在这些时段内，RTC IC必须提供可靠性能，通常会从辅助电池或超级电容器获取电源。如预期一样，对于大多数实时时钟设计来说，功耗是一个重要因此，此外还包括精度、可靠性和小封装尺寸。现代大部分RTC通过支持串行接口来减少所需的引脚数量。我们提供多种高度准确、低功耗、小封装、基于微机电系统(MEMS)的实时时钟，以满足您的解决方案需求。
