Product Details

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

    Design Tools

    ADIsimDDS (Direct Digital Synthesis)

    ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. ADIsimDDS calculates the required FTW, given the reference clock frequency and desired output frequency. This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters.
