AD9857,pdf datasheet (CMOS 200

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 industry-standard 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 −40°C to +85°C.
