Overview
The AD9516-0BCPZ-REEL7 is a high-performance clock generator and fanout buffer produced by Analog Devices Inc. This integrated circuit is designed to provide low jitter and low phase noise, making it ideal for applications that require precise clock distribution. The device features an on-chip phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) that tunes from 2.55 GHz to 2.95 GHz. It also supports the use of an external VCO/VCXO up to 2.4 GHz. The AD9516-0BCPZ-REEL7 is packaged in a 64-lead LFCSP (9x9 mm) and operates from a single 3.3 V supply, with optional separate power supplies for LVPECL outputs and external VCOs.
