Analog Devices Inc. AD9166 Signal Generator

Analog Devices Inc. AD9166 Signal Generator is a high-performance, wideband, and on-chip vector signal generator composed of a high-speed JESD204B Serializer/Deserializer (SERDES) interface. This signal generator features a flexible 16-bit digital datapath, Inphase/Quadrature (I/Q) Digital-to-Analog Converter (DAC) core, and an integrated differential to a single-ended output buffer amplifier. The AD9166 signal generator is configured for lower data-rates while maintaining high-DAC clock-rates to ease the filtering requirements and reduce overall system size, weight, and power. Typical applications include instrumentation, electronic test and measurements, electronic warfare, broadband communication systems, and load oscillator drivers.
