Overview
The AD9516-5BCPZ-REEL7, produced by Analog Devices Inc., is a high-performance 14-output clock generator designed to provide subpicosecond jitter performance. This device is part of the AD9516 family and is optimized for applications requiring low jitter and phase noise, such as data converters, wireless infrastructure, instrumentation, and networking.
The AD9516-5 features an on-chip PLL that can be used with an external VCO/VCXO of up to 2.4 GHz, ensuring flexible clock generation and distribution. The device operates from a single 3.3 V supply and can accommodate an external VCO with an extended voltage range by connecting the charge pump supply (VCP) to 5.5 V.
