Overview
The AD9520-3BCPZ-REEL7 is a high-performance clock generator from Analog Devices Inc., designed to provide multioutput clock distribution with subpicosecond jitter performance. This device features an on-chip phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) that tunes from 1.72 GHz to 2.25 GHz. It also supports the use of an external VCO/VCXO up to 2.4 GHz. The AD9520-3BCPZ-REEL7 is packaged in a 64-lead LFCSP and operates from a single 3.3 V supply, making it suitable for a wide range of high-frequency applications.
