Kit Overview

The Analog Devices AD9959/PCBZAD9959/PCBZ Evaluation Board for 4-Channel 500 MSPS DDS with 10-Bit DACs uses AD9959AD9959. The AD9959 is a multichannel frequency synthesizer that incorporates four synchronous direct digital synthesis (DDS) cores with many user-programmable functions.

The Evaluation board software provides a graphical user interface for easy communication with the device along with many user-friendly features such as the “mouse-over effect.” Many elements of the software can be clarified by placing your mouse over the element.

The AD9959AD9959, 4 Channel 500 MSPS DDS with 10-bit DACs:

The AD9959 consists of four direct digital synthesizer (DDS) cores that provide independent frequency, phase, and amplitude control on each channel. This flexibility can be used to correct imbalances between signals due to analog processing, such as filtering, amplification, or PCB layout-related mismatches. Because all channels share a common system clock, they are inherently synchronized. Synchronization of multiple devices is supported.
The AD9959 can perform up to a 16-level modulation of fre-quency, phase, or amplitude (FSK, PSK, ASK). Modulation is performed by applying data to the profile pins.
The AD9959 serial I/O port offers multiple configurations to provide significant flexibility
The AD9959 uses advanced DDS technology that provides low power dissipation with high performance.
The device incorporates four integrated, high speed 10-bit DACs with excellent wideband and narrow-band SFDR. Each channel has a dedicated 32-bit frequency tuning word, 14 bits of phase offset, and a 10-bit output scale multiplier.
The DDS acts as a high resolution frequency divider with the REFCLK as the input and the DAC providing the output.

Key Applications: AD9959 performance evaluation, GUI control panel for learning AD9959 programming
