AD9857

CMOS 200 MSPS 14-Bit Quadrature Digital Upconverter

Analog Devices 

AD9857

GENERAL DESCRIPTION

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.
