Overview
The AD9517-3BCPZ, produced by Analog Devices Inc., is a 12-output clock generator that integrates a 2.0 GHz voltage-controlled oscillator (VCO) and a phase-locked loop (PLL). This component is designed to provide multi-output clock distribution with subpicosecond jitter performance, making it ideal for applications requiring high precision and low phase noise. The AD9517-3 features an on-chip VCO that tunes from 1.75 GHz to 2.25 GHz, with the option to use an external VCO/VCXO up to 2.4 GHz. It is particularly beneficial for applications such as high-performance wireless transceivers, data converters, and advanced test equipment (ATE) and instrumentation.
