Function
POWER SUPPLY
2
VDD
Positive power supply for the analog section and the digital interface sections. The on board 2.5 V
regulator is also supplied from VDD. VDD can have a value from +2.3 V to +5.5 V. A 0.1 μF and
10 μF decoupling capacitor should be connected between VDD and AGND.
The digital circuitry operates from a +2.5 V power supply. This +2.5 V is generated from VDD
using an on board regulator (when VDD exceeds +2.7 V). The regulator requires a decoupling
capacitor of typically 100 nF, which is connected from CAP/2.5V to DGND. If VDD is equal to
or less than +2.7 V, CAP/2.5V should be tied directly to VDD.
Digital Ground.
Analog Ground.
ANALOG SIGNAL AND REFERENCE
1
COMP
A DAC Bias Pin. This pin is used for de-coupling the DAC bias voltage.
10
VOUT
Voltage Output. The analog and digital output from the AD9833 is available at this pin. An
external load resistor is not required as the device has a 200W resistor on board.
DIGITAL INTERFACE AND CONTROL
5
MCLK
Digital Clock Input. DDS output frequencies are expressed as a binary fraction of the frequency of
MCLK. The output frequency accuracy and phase noise are determined by this clock.
6
SDATA
Serial Data Input. The 16-bit serial data word is applied to this input.
7
SCLK
Serial Clock Input. Data is clocked into the AD9833 on each falling SCLK edge.
8
FSYNC
Active Low Control Input. This is the frame synchronisation signal for the input data. When
FSYNC is taken low, the internal logic is informed that a new word is being loaded into the
device.
