Analog Devices Inc. AD9516-3BCPZ

Description
The AD9516-3 is a multi-output clock generator with subpicosecond jitter performance. It features an on-chip PLL and VCO that tunes from 1.75 GHz to 2.25 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.
The AD9516-3 emphasizes low jitter and phase noise to maximize data converter performance. It can also benefit other applications with demanding phase noise and jitter requirements.
