Description
The AD9857AST is a complete quadrature digital upconverter device designed 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. This electronic component model 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.
