The AD9857 integrates a high-speed Direct Digital Synthesizer (DDS), a high-performance, high-speed 14-bit digital-to-analog converter (DAC), clock multiplier circuitry, digital filters, and other DSP functions onto a single chip, to form a complete quadrature digital upconverter device. The AD9857 is intended to function as a universal I/Q modulator and agile upconverter, single-tone DDS, or interpolating DAC for communications applications, where cost, size, power dissipation, and dynamic performance are critical attributes. The AD9857 offers enhanced performance over the industrystandard AD9856, as well as providing additional features. The AD9857 is available in a space-saving surface-mount package and is specified to operate over the extended industrial temperature range of 40C to +85C.
