Overview
The AD9517-4ABCPZ, produced by Analog Devices Inc., is a high-performance 12-output clock generator that integrates a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO). This component is designed to provide subpicosecond jitter performance, making it ideal for applications requiring low phase noise and jitter. The on-chip VCO tunes from 1.45 GHz to 1.80 GHz, and an external VCO/VCXO up to 2.4 GHz can also be used. The AD9517-4 is particularly beneficial for maximizing data converter performance and other applications with stringent phase noise and jitter requirements.
