Overview
The AD9520-1BCPZ, produced by Analog Devices Inc., is a high-performance clock generator and fanout distribution IC. This device is designed to provide multiple clock outputs with subpicosecond jitter performance, making it suitable for a wide range of applications requiring precise clocking. The AD9520-1 features an on-chip PLL and VCO, which can be tuned from 2.27 GHz to 2.65 GHz, and also supports the use of an external VCO/VCXO up to 2.4 GHz. The IC is available in a 64-lead LFCSP package and operates from a single 3.3 V supply, with an optional separate output driver power supply ranging from 2.375 V to 3.465 V.
