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 Ohm 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.
The AD9166 is configured using a common SPI interface that monitors the status of all registers. The AD9166 is offered in a 324-ball, 15 mm × 15 mm, 0.8 mm pitch BGA_ED package.
