Overview
The AD9518-1ABCPZ-RL7 is a high-performance clock generator 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 low phase noise and jitter. The device features an on-chip phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) that tunes from 2.30 GHz to 2.65 GHz. It is available in a 48-lead LFCSP package and operates from a single 3.3 V supply.
