General Description
AD9953 General Description
The AD9953 is a Direct Digital Synthesizer (DDS) featuring a 14-bit DAC operating up to 400MSPS. The AD9953 uses advanced DDS technology, coupled with an internal high-speed, high performance D/A converter to form a digitallyprogrammable, complete high-frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform at up to 200 MHz. 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 includes an integrated 1024x32 Static RAM to support flexible frequency sweep capability in several modes.
The AD9953 is specified to operate over the extended industrial temperature range of -40° to +85°C.

* Absolute maximum ratings are limiting values, to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional operability under any of these conditions is not necessarily implied. Exposure of absolute maximum rating conditions for extended periods of time may affect device reliability.
