Evaluation Board for the AD9835

Direct Digital Synthesizer

EVAL-AD9835EB

Components on the AD9835 Evaluation Board include a

50 MHz oscillator which provides the MCLK for the

AD9835. T he user can remove this oscillator, if required,

and drive the AD9835 with a different clock oscillator or

an external clock source via a BNC connector. A digital

buffer is also on the board so that the signals from the

edge connector are buffered.

T his Application Note describes the evaluation board for

the AD9835 Direct Digital Synthesizer (DDS). T he

AD9835 is a numerically controlled oscillator employing

a phase accumulator, a sine look-up table and a 10-bit D/

A converter. T he part can be operated with clock

frequencies up to 50 MHz. Both phase modulation and

frequency modulation can be performed with the AD9835.

Full data on the AD9835 is available in the AD9835

datasheet available from Analog Devices and should be

consulted in conjunction with this Application Note when

using the evaluation board.

P ower Supplies

T his evaluation board has two analog power supply inputs:

AV_DDand AGND. AV_DDequals +5V or +3.3V and is used

to provide the AV_DDfor the AD9835. DGND and DV_DD

connections are also available. T he DV_DDis used to

provide the DV_DDfor the AD9835, the 50 MHz oscillator

and the DV_DDfor the digital buffer. DGND and AGND

are connected under the AD9835. T herefore, it is

recommended not to connect AGND and DGND

elsewhere in the system.

T he evaluation board interfaces to the parallel port of an

IBM compatible PC. Software is available with the

evaluation board which allows the user to easily program

the AD 9835.

All power supplies are decoupled to ground. AV_DDand

DV_DDare decoupled using 10µF tantalum capacitors and

0.1µF ceramic capacitors at the input to the evaluation

board. T he power supplies are again decoupled using

0.1µF capacitors at the AD9835, the crystal and the logic.
