Overview
The AD9517-2ABCPZ-RL7, produced by Analog Devices Inc., is a high-performance 12-output clock generator with an integrated 2.2 GHz voltage-controlled oscillator (VCO). This device is designed to provide low jitter and phase noise, making it ideal for applications requiring precise clock distribution. The AD9517-2 features an on-chip phase-locked loop (PLL) and supports both internal and external VCO/VCXO configurations up to 2.4 GHz. It is packaged in a 48-lead LFCSP (Lead Frame Chip Scale Package) and operates from a single 3.3 V supply.
