Analog Devices AD9856 Datasheet Handbook Rev C
The AD9856 integrates a high‑speed direct digital synthesizer, a 12‑bit digital‑to‑analog converter, clock‑multiplier circuitry and digital filters to form a complete quadrature upconverter. It is offered in a low‑profile 48‑lead LQFP package and operates from a single +3 V supply over an industrial temperature range.
The document provides detailed specifications, pin configurations, functional block descriptions, typical performance plots, and mechanical dimensions, along with an ordering guide and evaluation‑board information.
