Analog Devices Inc. AD9525 低抖动时钟发生器
Analog Devices AD9525低抖动时钟发生器，具有业内最好的抖动性能和最快的输出速度，旨在满足长期演进(LTE)和多载波GSM基站设计的转换器时钟要求。AD9525提供低功耗、多路输出时钟分配功能，具有低抖动性能，并且片内集成锁相环（PLL），可以配合外部VCO或VCXO使用。VCO输入和八个LVPECL输出最高工作频率为3.6 GHz。所有输出共用一个分频器，分频范围为1到6。AD9525提供了一个专用输出，可用于提供一个用于重置或同步数据转换器的可编程信号。输出信号可以通过一个SPI写入操作激活。该款低抖动时钟发生器的工作温度范围为−40℃至+85℃的扩展工业温度范围。
The VCO input and eight LVPECL outputs can operate up to a frequency of 3.6GHz. All outputs share a common divider that can provide a division of 1 to 6. ADI AD9525 offers a dedicated output that can be used to provide a programmable signal for resetting or synchronizing a data converter. The output signal is activated by a SPI write. This low jitter clock generator operates over the extended industrial temperature range of -40°C to +85°C.
