KIT DIY DDS AD9910 V2 https://www.ebay.com/itm/184287819742 DDS AD9910 Arduino Shield Signal Generator DDS (Direct Digital Synthesis) Analog Devices AD9910 Arduino Shield by GRA & AFCH Open source software and scheme always available on GitHub: https://github.com/afch/DDS-AD9910-Ar... Easy connection to Arduino Mega without additional wires and converters. All functions of the DDS AD9910 are brought to the contacts of the Arduino Mega thanks to this you can fully reveal all the capabilities of the DDS AD9910. Key Benefits: Low harmonics no more than -60dB. An output RF transformer is used for the correct operation of the current mirror. Small spur 4 layer board. Signal lines TOP and Bottom, inner layers Ground and Power. Low Noise LDO Stabilizers 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 4 types of generation are possible (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, EGEN – external generator up to 1.5 GHz. NOTE: 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 synthesizer is capable to generate pure sine, AM or FM modulated signal. 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 (heatsink is recommended) 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
