Analog Devices Inc. AD9518-4ABCPZ-RL7

Description
The AD9518-4 is a multi-output clock distribution device with subpicosecond jitter performance. It features an on-chip PLL and VCO that tunes from 1.45 GHz to 1.80 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used. The AD9518-4 emphasizes low jitter and phase noise to maximize data converter performance.

Features
