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 digitally-
programmable, 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
ABSOLUTE MAXIMUM RATINGS

Digital Input Voltage............................... -0.7 V to +Vs
Digital Output Current ....................................... 5 mA
*
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.
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.
