Kit Overview

The Analog Devices AD9914/PCBZAD9914/PCBZ Evaluation Board uses AD9914AD9914 which is a 3.5 GSPS DDS with a 12-bit DAC. The evaluation board software provides a graphical user interface (GUI) for easy communication with the device along with many user-friendly features such as the mouse-over effect.

The AD9914AD9914 3.5 GSPS Direct Digital Synthesizer with 12-bit DAC:

The AD9914 is a direct digital synthesizer (DDS) featuring a 12-bit DAC targeted at operating up to 3.5 GSPS.
The AD9914 uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a digitally programmable, complete high frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform at up to 1.4 GHz.
The AD9914 is designed to provide fast frequency hopping and fine tuning resolution (32 bit in standard mode, 64 bit capable using programmable modulus mode).
The AD9914 also offers fast phase and amplitude hopping capability. The frequency tuning and control words are loaded into the AD9914 via a serial or parallel I/O port.
The AD9914 also supports a user defined linear sweep mode of operation for generating highly linear swept waveforms of frequency, phase or amplitude. A high speed parallel data input port is included enabling high data rates for polar modulation schemes and fast reprogramming of the phase, frequency and amplitude tuning words.
The AD9914 is specified to operate over the extended industrial temperature range

Key Applications: Agile LO frequency synthesis, Programmable clock generator, FM chirp source for radar and scanning systems, Test and measurement equipment, Acousto-optic device drivers, Polar modulator, Fast frequency hopping
