Overview
The AD9517-3ABCPZ from Analog Devices Inc. is a 12-output clock generator designed to provide high-performance clock distribution with integrated timing solutions. This device features an on-chip phase-locked loop (PLL) and a voltage-controlled oscillator (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 optimized for low jitter and phase noise, making it ideal for applications requiring precise timing, such as data converters and high-performance instrumentation.
