$18.00
  • Model: EF03059
  • Shipping Weight: 30g
  • 144 Units in Stock

Description

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 paralle 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 channles square wave output and 2 chanles sine wave output
  • Sine wave: 0-40M; Square wave: 0-1M
  • Using 70MHz low pass filter, the waveform's SN better clear
  • Parallel and Seiral data bus selction
  • Duty cycle adjustedable - 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
