GENERAL DESCRIPTION

The AD9856 integrates a high speed, direct digital synthesizer (DDS), a high performance, high speed, 12-bit digital-to-analog converter (DAC), clock multiplier circuitry, digital filters, and other DSP functions on a single chip to form a complete quadrature digital upconverter device. The AD9856 is intended to function as a universal I/Q modulator and agile upconverter for communications applications where cost, size, power dissipation, and dynamic performance are critical attributes.
