• Product details

  AD9953is a direct digital frequencysynthesizer(DDS), which contains a 14-bit DAC and operates at speeds up to 400 MSPS. Using advanced DDS technology and a high-speed, high-performance DAC, the device forms a digitally programmable complete high-frequency synthesizer capable of generating frequency-agile analog output sine waves up to 200 MHz. It includes an integrated 1024 × 32 static RAM that supports flexible sweep in multiple modes. The device is designed to provide fast frequency hopping and precision tuning resolution (32-bit frequency tuning words). Both the frequency tuning word and the control word are loaded into the AD9953 through the serial I/O port.

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