Product Summary

The AD9857ASTZ 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 AD9857ASTZ 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 AD9857ASTZ offers enhanced performance over the industrystandard AD9856, as well as providing additional features. Applications are (1)HFC data, telephony, and video modems; (2)wireless base station; (3)agile, L.O. frequency synthesis; (4)broadband communications.
