Description:

The version of STM32 function evaluation board now support RAM operation,generate any signal below 2 MHZ .in the future new version will add some other new functions based on customer feedback. 

 Characteristics of the module: 

     1. The AD9910 module is created by senior engineers with their greatest efforts. the advantage of PCB good appearance, reasonable layout design, and the use of good materials.We pursues is all in the details; 

    2.The AD9910 module is totally controlled by IO, which is suited to the full functionality of the needs of customers and for secondary development; and there is no need to concern the AD9910 module design; 

     3. It is compatible with most of the functions of ADI OEM upper software, and it can achieve most of the functions of chip AD9910 and can quickly make the characteristics of AD9910 understood; the main functions are:

a. automatic linear frequency / phase / amplitude scanning function;

b、Below 2MHZ arbitrary signal generator(MAX:10Mhz The higher the frequency, the worse the quality of the signal)

C. 8 kinds of frequency, phase and amplitude modulation mode;

d. single frequency mode, which supports frequency, phase and amplitude to be adjusted;

e、Support RAM operation;

 f. with parameters preserved function (the official version is without this function); 

      4. Function evaluation board with USB interface can directly use USB for power supply, which is easy to use; 

     . AD9910 chip function introduction: 

• 1 GSPS internal clock speed (up to 400 MHz analog output)
• Integrated 1 GSPS, 14-bit DAC
• 0.23 Hz or better frequency resolution
• Phase noise ≤ −125 dBc/Hz @ 1 kHz offset (400 MHz carrier)
• Excellent dynamic performance with
• >80 dB narrow-band SFDR
• Serial input/output (I/O) control
• Automatic linear or arbitrary frequency, phase, and
• amplitude sweep capability
• 8 frequency and phase offset profiles
• Sin(x)/(x) correction (inverse sinc filter)
• Integrated 1024 word × 32-bit RAM
• PLL REFCLK multiplier
• Parallel datapath interface
• Phase modulation capability
• Amplitude modulation capability

 Module measured waveform:

 Module application

• Agile local oscillator (LO) frequency synthesis
• Programmable clock generators
• FM chirp source for radar and scanning systems
• Test and measurement equipment
• Acousto-optic device drivers
• Polar modulators
• Fast frequency hopping；

 Module performance parameters: 

     1. The evaluation board and AD9910 module are both supplied by 5V power which means they can be independently supplied directly through the USB (5V supply) or combing the evaluation board with the AD9910 module (It is recommended to adopt the latter power supply mode if the working frequency is relatively higher or the work lasts longer term); 

     2. Output frequency 0---400M, resolution 0.23HZ or above; 

      3. The output range 0 - 1VPP (1M high resistance), the amplitude will decrease with the frequency, and the resolution of the magnitude is 16384. 

     4. Phase resolution: 0.0055 degree.

 packing: 

     1. AD9910 module x1

     2. Function evaluation board x 1

    3. USB cable x1
