Overview
The AD9517-1ABCPZ-RL7, produced by Analog Devices Inc., is a 12-output clock generator that integrates a 2.5 GHz Voltage-Controlled Oscillator (VCO) and a Phase-Locked Loop (PLL). This device is designed to provide high-performance clock distribution with subpicosecond jitter performance, making it ideal for applications requiring low jitter and phase noise.
The AD9517-1 features an on-chip VCO that tunes from 2.30 GHz to 2.65 GHz, and it also supports the use of an external VCO/VCXO up to 2.4 GHz. The device is available in a 48-lead LFCSP package and operates from a single 3.3 V supply, with the option to use a separate LVPECL power supply from 2.5 V to 3.3 V and a charge pump supply up to 5 V for external VCOs.
