The AD9953 is a direct digital synthesizer (DDS) featuring a 14-bit DAC operating up to 400 MSPS. The AD9953 uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a digitally programmable, complete high frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform at up to 200 MHz. The AD9953 includes an integrated 1024 × 32 static RAM to support flexible frequency sweep capability in several modes. The AD9953 is designed to provide fast frequency hopping and fine tuning resolution (32-bit frequency tuning word). The frequency tuning and control words are loaded into the AD9953 via a serial I/O port.

The AD9953 is specified to operate over the extended industrial temperature range of –40°C to +105°C.

Applications

  • Agile VHF/UHF LO frequency synthesis
  • FM chirp source for radar and scanning systems
  • Nonlinear-shaped PSK/FSK modulator
  • Test and measurement equipment
