AD9954

Direct Digital Synthesis (DDS) Featured Products

AD995x – the new full-featured DDS Family...
400 MHz Sampling Rate, <200 mW Power

... performance

  • synthesizes fundamental output frequencies and clocks up to 160 MHz
  • one-tenth the power dissipation of the previous generation enables designers to use multiple DDSs on a single PCB
  • master-slave function allows full synchronization of multiple DDS devices automatically
  • 32-bit frequency tuning word; 14-bit control word for output amplitude and phase offset

... where it matters

  • agile LO frequency synthesis
  • FM chirp source for radar and scanning systems
  • satellite communications
  • test and measurement equipment
