Full-Featured Evaluation Board for the AD9830
Various Linking Options
PC Software for Control of AD9830
INTRODUCTION
This Application Note describes the evaluation board for the
AD9830 Direct Digital Synthesizer (DDS). The AD9830 is a
numerically controlled oscillator employing a phase
accumulator, a sine look-up table and a 10-bit D/A converter.
The part can be operated with clock frequencies up to 50
MHz. Both phase modulation and frequency modulation can
be performed with the AD9830. Full data on the AD9830 is
available in the AD9830 datasheet available from Analog
Devices and should be consulted in conjunction with this
Application Note when using the evaluation board.
The 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 AD9830.
Components on the AD9830 Evaluation Board include a 50

source via a BNC connector. Latches (74HC574) are also on
the board, these latches being used to hold the 16-bit data
word being written from the PC to the AD9830.
OPERATING THE AD9830 EVALUATION BOARD
Power Supplies
This evaluation board has two analog power supply inputs:
AVDD and AGND. AVDD equals +5 V and is used to
provide the AVDD for the AD9830. DGND and DVDD
connections are also available. The DVDD is used to provide
the DVDD for the AD9830, the 50 MHz oscillator and the
DVDD for the logic chips. DGND and AGND are
connected at the AD9830. Therefore, it is recommended not
to connect AGND and DGND elsewhere in the system.
All power supplies are decoupled to ground. AVDD and
DVDD are decoupled using 10 μ F tantalum capacitors and
0.1 μ F ceramic capacitors at the input to the evaluation board.
The power supplies are again decoupled using 0.1 μ F
capacitors at the AD9830, the crystal and the logic.
MHz oscillator which provides the MCLK for the AD9830.
The user can remove this oscillator, if required, and drive the
AD9830 with a different clock oscillator or an external clock
