Overview
The AD9517-4ABCPZ-RL7 is a high-performance clock generator and synthesizer produced by Analog Devices Inc. This component is designed to provide multi-output clock distribution with subpicosecond jitter performance, making it ideal for applications requiring precise timing and low phase noise. The device features an integrated 1.6 GHz voltage-controlled oscillator (VCO) and a phase-locked loop (PLL), which can be optionally supplemented with an external VCO/VCXO up to 2.4 GHz. It operates from a single 3.3 V supply and is available in a 48-lead LFCSP package.
