AD9954 is a direct digital frequency synthesizer (DDS), using the latest technology, built-in a high-speed high-performance DAC, form a complete digital programmable, high-frequency synthesizer, can produce up to 150MHz frequency agile analog output sine wave .It can achieve fast frequency hopping, and also has precise frequency tuning (0.01Hz or higher resolution) and phase harmonics (0.022 ° interval), the standard program is adjustable 1hz. If users need higher precision, they need to change the program by themselves. Can be programmed through a high-speed serial I / O port. The device's built-in static RAM supports flexible frequency sweep functions in multiple modes and supports user- defines linear scan modes; At the same time, an on-chip high-speed comparator is built in, suitable for applications requiring square wave output. With the help of the on-chip oscillator and PLL circuit, users can create the system clock of the device in various ways. AD9954's rated operating temperature range is the extended industrial temperature range
Precautions for using the module：
(1) The module is a low-power consumption module, and the power supply does not exceed 5.5 V.(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 on BNC cable to directly observe the output signal for the output signal. Poor contact or poor quality wires can cause signal attenuation or excessive noise.(4) The supplied code is only used for supporting main control board, and does not offer a microcontroller tutorial; additional functions have to be developed by yourself.(5) If you simply need to test the function of the module, it is recommended to use the control board from 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 get the function.Module test chart：
Frequently asked Questions：
Q: Can the main frequency and output amplitude of the module be set?A: The main frequency of the module is determined by the input clock and the program together. The module can input the clock externally, and the onboard standard clock is 20MHz; The program control frequency is 20 times, that is, the standard main frequency is 400MHz. The frequency changes the main frequency, and the output amplitude can be controlled by changing the 14-bit amplitude register. You need to change the program yourself.Q: Can the module achieve frequency sweep? Is the space wave duty cycle adjustable?A: The module can realize frequency sweep, the code provided by our shop can support frequency sweep. The square wave amplitude and duty cycle of the module cannot be adjusted, and the frequency and amplitude of the sine wave can be adjusted.Q: Can BIN and other modulations be carried out oriented?A: You can achieve low-speed AM modulation by changing the amplitude register, and it has several sweep modes. The standard code is software single-tone sweep. Other modes have to be programmed by yourself.
