DIY KIT for DDS AD9910 Arduino Shield Signal Generator. P to sine wave output 600Mhz. Attention needs a forced cooling. DDS AD9910 Arduino Shield RF Signal Generator. DDS (Direct Digital Synthesis) Analog Devices AD9910 Arduino Shield by GRA & AFCH.

Easy connection to Arduino MEGA 2560 without additional wires and converters. All functions of the DDS AD9910 are brought to the contacts of the Arduino MEGA. With this you can fully reveal all the capabilities of the DDS AD9910 Shield.

Opensource Software available on our GitHub repository: afch/DDS-AD9910-Arduino-Shield. Video review on our YouTube channel: youtu.

AD9910 Shield Board (Bare PCB). Set of Parts and Components (Electronics, Screws, Nuts, Spacers). OLED Display (optional , choose in selector). Arduino MEGA Board (optional , choose in selector). Clock Chip (optional , choose in selector).

BOM List of Parts and Components for DIY KIT. We recommend to use RF Amplifier with our DDS Shield Boards. (RF Amplifier 8-2000 MHz, GAIN = 20 dB, P = +20 dBm MMIC MRFA89 SOT-89).

Low harmonics no more than -60dBc. An output RF transformer is used for the correct operation of the current mirror. Signal lines TOP and Bottom, inner layers Ground and Power. Separate power supply for all analog and digital lines (1.8V and 3.3V), 5 pcs IC voltage stabilizers are used. Additionally, there is an RF Ferrite bead interchange.

High-speed decoupling Level converter and TTL 5V matching. Types of possible reference oscillators (choose one of them in the selector). XO Crystal 25 MHz 20 ppm internal oscillator with PLL at 1 GHz. TCXO 10 MHz 1 ppm external oscillator PLL at 1 GHz (up to 1.5 GHz).

EGEN external generator up to 1.5 GHz. (To connect an external clock source of up to 1.5 GHz, this source is NOT INCLUDED). OCXO Oven Controlled Crystal Oscillators deliver the ultimate piezo electric performance with stabilities down to less than ±1 ppm. Additionally balancing transformer is used for TCXO, EGEN and OCXO options.

Easy to connect OLED display. Control buttons for control via the program menu.

The software allows you to select and configure the frequency of the clock generator through the user menu (without the need to recompile the program). Any settings can be stored in non-volatile EEPROM memory (located at Arduino Mega). Basic settings are applied and saved automatically. This shield support overclocking the AD9910 core to 1.5 GHz. DDS AD9910 Shield has ability to generate a signal up to 600 MHz with a core overclocking up to 1.5 GHz.

(to suppress harmonics, it is recommended to overclock the AD9910 for frequencies above 400 MHz). Has ability to increase output power by +4 dBm when DAC Current HI is activated. Since the intrinsic phase noise of DDS is obviously less than that of PLL generators, the final value is highly dependent on the clock source. In order to achieve the values stated in the datasheet for AD9910, we strictly adhered to all recommendations from Analog Devices.

When designing our DDS AD9910 Arduino Shield we have followed these requirements. PCB layout in 4 layers, separate power supply of all 4 power lines (3.3 V digital, 3.3 V analog, 1.8 V digital, and 1.8 V analog).

Figure 16 shows the noise level when using the built-in PLL in DDS. The PLL multiplies the frequency of a 50 MHz generator by 20 times. We use a similar frequency 40 MHz (x25 Multiplier) or 50 MHz (x20 Multiplier) from TCXO which gives even more stability. Figure 15 shows the noise level when using an external reference clock 1 GHz, with the PLL off. DDS AD9910 Arduino Shield Phase Noise.

That is, when using an external clock phase noise by 15 dBc better (lower). That is, when using an external clock phase noise by 34 dBc better (lower). Conclusion: when using external clocking, you can get much lower phase noise than using the built-in PLL. But do not forget that in order to achieve such results, increased requirements are put forward to the external generator. DDS AD9910 Core Clock Menu.
