Analog Devices AD9520-1 Clock Generator Datasheet
The AD9520-1 provides a multi‑output clock distribution function with sub‑picosecond jitter performance. It integrates a PLL and an on‑chip VCO that tunes from 2.27 GHz to 2.65 GHz, and can also use an external VCO/VCXO up to 2.4 GHz. The device offers twelve LVPECL outputs (configurable as CMOS) organized in four groups, each with programmable dividers and phase delay.
Typical applications include low‑jitter clock distribution for high‑speed serial links (SONET, 10 GbE, etc.), clocking of high‑performance ADCs/DACs, wireless transceivers, and test equipment. The AD9520-1 operates from a single 3.3 V supply over an industrial temperature range (‑40 °C to +85 °C).
