Product Summary
The AD9953YSVZ is a direct digital synthesizer (DDS) featuring a 14-bit DAC operating up to 400 MSPS. The AD9953YSVZ 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 AD9953YSVZ includes an integrated 1024 × 32 static RAM to support flexible frequency sweep capability in several modes. The AD9953YSVZ 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 AD9953YSVZ via a serial I/O port. The AD9953YSVZ is specified to operate over the extended industrial temperature range of –40℃ to +105℃.
