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.
