AD9850 DDS SIGNAL GENERATOR

DESCRIPTION

PROJECT NAME:  AD9850 DDS Signal Generator Module 0-40MHz 2 Sine Wave And 2 Square Wave Output

The DDS module is base on AD9850 which is provided by ADI Company and common used in many DDS module. The chip provide 0-40MHz measurement capability, the AD9850's innovative high speed DDS core provides a 32-bit frequency tuning word, which results in an output tuning resolution of 0.0291Hz for a 125MHz reference clock input.

This module provide you a ready made hardware and you can use serial or parallel pins on board to control the AD9850 for different frequency out put. The duty can be adjust by a adjustable resistor - which change the adjust voltage level of the comparer.

Features:

·         2 channels square wave output and 2 channels sine wave output

·         Sine wave: 0-40M; Square wave: 0-1M

·         Using 70MHz low pass filter, the waveform's SN better clear

·         Parallel and Serial data bus selection

·         Duty cycle adjustable - Comparator reference input voltage generated by the variable resistor

·         DA reference Pin12 elicit, easy adjustment wave out amplitude

·         Size: 42 x 30 x 1.6 mm

specification:
