AD9957 Datasheet 1 Gsps Quadrature Digital Upconverter

Manufacturer: Analog Devices

Overview: Data Sheet 1 GSPS Quadrature Digital Upconverter with 18-Bit I/Q Data Path and 14-Bit.

General Description

The AD9957 functions as a universal I/Q modulator and agile upconverter for munications systems where cost, size, power consumption, and dynamic performance are critical.

The AD9957 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.

It provides baseband upconversion for data transmission in a wired or wireless munications system.

Key Features

  • 1 GSPS internal clock speed (up to 400 MHz analog output) Integrated 1 GSPS 14-bit DAC 250 MSPS input data rate Phase noise ≤.
  • 125 dBc/Hz (400 MHz carrier @ 1 kHz offset) Excellent dynamic performance >80 dB narrow-band SFDR 8 programmable profiles for shift keying Sin(x)/(x) correction (inverse sinc filter) Reference clock multiplier Internal oscillator for a single crystal operation Software and hardware controlled power-down Integrated RAM Phase modulation capability Multichip synchro.
