AD9851 DDS Signal Generator Module Circuit
WARNING - it has come to light that there are versions of these modules with 3v3 oscillators. Click link for one builders mods DDS 3v3 mods. (Click Browser "back" button to return to this page)http://www.vk5tm.com/homebrew/dds/dds.phpDDS Signal Generator
A DDS based Signal Generator that runs from 1Hz to 60MHz in 1Hz steps -
The AD9850 Module uses a 125MHz oscillator module while the AD9851 module uses a 30MHz oscillator. For all intents and purposes, they look identical unless you have a magnifying glass in hand.

This is a low cost yet versatile function generator capable of producing many different waveforms. As an easy-to-use tool operation of FG085 is very simple and straightforward. It is an ideal test/experiment tool for electronics hobbyists and students.
Specification
Frequency range: 0 - 200KHz (Sine)
Frequency resolution: 1Hz
Period resolution: 1ms
Amplitude range: 0 - 10V peak-to-peak
Offset range: -5V - +5V
Memory depth: 256 bytes
Sample rate: 2.5Msps
Output impedance: 50 ohm
Power supply voltage: DC 15V
Current consumption: < 150mA (without loading)
Dimension: 155 X 55 X 30 mm
Net weight: 100 gram
Features implemented as of current firmware
Generating continuous Sine, Square, Triangle, Ramp (up and down), and Staircase (up and down) signals
Generating servo test/control signals with user defined pulse width, amplitude, and cycle [ NEW ]
Setting of frequency (or period), amplitude, and offset is done with digits - quick and straightforward
Frequency (period), amplitude, and offset can be incrementally adjusted up and down with rotary encoder
Settings are memorized after power down.
Can be used as an adjustable DC voltage source by setting amplitude to 0
Features to be implemented (hardware support already in place)
Generating arbitrary signals
Generating special test signals NTSC/PAL video synchronous signal, and more
Generating sweeping signal with continuous phase
USB connection for waveform download and control
Programmable frequency, amplitude, and offset
Synchronous output
