Short description: Easy to connect OLED displayOne encoder for control via the program menuThe synthesizer is capable to generate sine wave, CMOS and HSTL signalsThe 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 automaticallyThis Shield Board support overclocking of the AD9912 core up to 1.3 GHz (heatsink is recommended)DDS AD9912 Shield has ability to generate a signal of up to 600 MHz with a core overclocking up to 1.3 GHz (to suppress harmonics it is recommended to overclock the AD9912 for frequencies above 400 MHz) Key Benefits: Low harmonics no more than -60dBc. An output RF transformer is used for the correct operation of the current mirrorThe AD9912 built-in 50 Ohm resistors achieve better noise and harmonic results than the AD9910Small spurs4 layer Board.

Therefore, when buying our DDS AD9912 Arduino Shield you can focus on the data from the datasheet on the AD9912. Figure below shows measured by Anritsu MS2781B the noise level when using the built-in PLL in DDS. The PLL multiplies the frequency of a 40 MHz generator by 26 times And another figure below (from Analog Devices AD9912 Datasheet Rev. F) shows the noise level when using an external reference clock 1 GHZ with the PLL OFF 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 OLED Display Menus: DDS AD9912 Core Clock Menu DDS AD9912 Sweep Menu DDS AD9912 Main Screen APPLICATIONS: Oscillator Ultra Low jitter Fout=50MHz -160dBc @ 10khz, Fout=400MHz -138dBc @ 10khz (external reference clock)Local oscillator (LO) for HAM RadioReceiver/Transmitter communicationsAgile local oscillator (LO) frequency synthesisFor teaching students at Universities and InstitutesSecure communicationsTest and measurement equipment Dear customers!If you have ANY questions, (PLEASE ASK us).
