Module description

 

The AD9910 is a direct digital frequency synthesizer (DDS) with a built-in 14 bit DAC that supports sampling rates up to 1 GSPS. AD9910 uses advanced DDS patented technology, which can greatly reduce power consumption without sacrificing performance. The DDS/DAC combination forms a digitally programmable high-frequency analog output frequency synthesizer that can generate frequency-agile sinusoidal waveforms at frequencies up to 400 MHz.

Users can access the same three signal control parameters used to control DDS, including: frequency, phase and amplitude. The AD9910 uses a 32-bit accumulator to provide fast frequency hopping and frequency tuning resolution. At 1 GSPS sampling rate, the tuning resolution is 0.23 Hz. This DDS also implements fast phase and amplitude switching.

Precautions for using the module

 

 

(1) The current consumption of the module is large, and the power supply needs to have a certain margin. It is recommended to use 5V1A or more for power supply.

(2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply.

(3) It is recommended to use the SMA to BNC cable to directly observe the output signal for the output signal. Poor contact or poor quality wires may cause signal attenuation or excessive noise.
 
(4) Due to the large power consumption and heat generation, pay attention to ventilation and heat dissipation for long-term work.
 
(5) If you need to simply test the function of the module, it is recommended to use it with the control board of our store. Power is supplied to the DDS module first, and then the power is supplied to the control board to generate a waveform. Long press the middle button to switch the function.

Frequently asked questions

 

Q: Can the main frequency and output amplitude of the module be adjusted?

 
A: The main frequency of the module is determined by the input clock and the program. The module can input the clock externally. The onboard default clock is 40MHz, and the program control frequency is 25 times, that is, the default main frequency is 1000MHz. The main frequency can be changed by modifying the input clock and frequency multiplier; the output amplitude can be controlled by modifying the 14-bit amplitude register. You need to modify the program yourself.
 
Q: Can the module achieve frequency sweep? Can any signal be generated?
 
A: The module can realize frequency sweep, the code provided by our store can support frequency sweep. The AD9910 chip has static RAM to support the generation of arbitrary waveforms, but it needs to be programmed by itself; there is no arbitrary waveform routine in this shop.
 
Q: Why is the phase difference of the waveform between channels not 180 degrees after the frequency is increased, and the amplitude is also reduced?
 
A: Due to the tolerance and delay effects of the filter, the frequency increase produces different phase shifts, so it is strictly the opposite only when the frequency is lower, and the DDS has a frequency decrease amplitude; this is the principle The problem.
