DDS AD9850 Signal Generator Module 0-40MHz Sine Wave and 2 Square Wave Output IC

AD9850 DDS Signal Generator Module is one of the small, low-cost boards to generate analog signals. This integrated board can be controlled through a microcontroller and can be digitally programmed using Direct Digital Synthesis Technology (DSS). AD9850 DDS Signal Generator Module is equipped with an AD9850 IC, a powerful Oscillator of 125MHz, and a DSS synthesizer. It operates at a very low power supply, thus finding applications in many small self-assembly projects to produce square and sine waves.

 Pin Configuration

Pin Name Function
VCC Supply pin
D0-D7 Data input pin
GND Reference potential pin
W-CLK Word Load Clock pin
FQ-UD Frequency Update pin
Data Serial data input through D7 pin
Reset Master reset pin
Sine-Wave 1 DAC Current Output pin
Sine-Wave 2 DAC Current Output pin
Square-Wave 1 DAC Complementary Output pin
Square-Wave 2 DAC Complementary Output pin
  • Input/Output pins: These are 8-bit data pins used to load data up to 32-bit frequency and 8-bit phase/control word. D7(MSB) also serves the purpose of loading a 40-bit serial data word.
  • W-CLK: A Word Load Clock is used to synchronize and load words serially or through parallel transmission.
  • FQ-UD: Frequency Update is used to update the frequency in the input data register when the clock has a rising edge. After updating, it reset the pointer to the word 0
  • DATA: This pin is connected to the D7 input pin. It is used to load serial data.
  • RESET: A master RESET is used to clear all the registers except for the IC’s input register by putting it into a HIGH state. Moreover, the outputs of DAC will be converted to Cosine 0 after some clocks.
