Product Overview

The AD9857ASTZ is a high speed Direct Digital Synthesizer (DDS) with a high performance, 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 power dissipation and dynamic performance are critical attributes.
  • 200MHz Internal clock rate
  • 14-bit Data path
  • Excellent dynamic performance - 80dB SFDR at 65MHz (±100kHz) AOUT
  • 4x to 20x Programmable reference clock multiplier
  • Reference clock multiplier PLL lock detect indicator
  • Internal 32-bit quadrature DDS
  • FSK capability
  • 8-bit Output amplitude control
  • Single-pin power-down function
  • Four programmable, pin-selectable signal profiles
  • SIN(x)/x correction (inverse SINC function)
  • Simplified control interface
  • 10MHz serial, 2-wire or 3-wire SPI®-compatible
  • Single-ended or differential input reference clock
  • Three modes of operation - Quadrature modulator mode, Single-tone mode, Interpolating DAC mode
