DAC Delivers 14 b at 2.5 GSamples/s

July 10, 2014
This board level DAC operates with 14-b resolution to 2.5 GSamples/s.

Model FMC223 is a digital-to-analog converter (DAC) in field-programmable-gate-array (FPGA) mezzanine card (FMC) format per VITA 57 requirements. The board is based on the AD9739 DAC from Analog Devices and designed for synthesizing broadband signals. It operates at 2.5 GSamples/s with 14-b resolution and operates with a 10-MHz clock input signal.

It can achieve a 2-V peak-to-peak differential analog output swing with single-tone noise level of -166 dBm/Hz at a 100-MHz IF and -162 dBm/Hz at a 1 GHz IF. The board, which is RoHS compliant, features a programmable digital-signal-processing (DSP) clock. It measures 2.71 × 3.01 in. (69.0 × 76.5 mm).
