AD9166:  DC to 9 GHz Vector Signal Generator - The AD9166 is a high performance, wideband, on-chip vector signal generator composed of a high speed JESD204B serializer/ deserializer (SERDES) interface, a flexible 16-bit digital datapath, a inphase/quadrature (I/Q) digital-to-analog converter (DAC) core, and an integrated differential to single-ended output buffer amplifier, matched to a 50 Ω load up to 10 GHz.

The DAC core is based on a quad-switch architecture, which is configurable to increase the effective DAC core update rate of up to 12.8 GSPS from a 6.4 GHz DAC sampling clock, with an analog output bandwidth of true dc to 9.0 GHz, typically. The digital datapath includes multiple interpolation filter stages, a direct digital synthesizer (DDS) block with multiple numerically controlled oscillators (NCOs) supporting fast frequency hopping (FFH), and additional FIR85 and inverse sinc filter stages to allow flexible spectrum planning.
