This product is a high-speed DDS module with a built-in 14bit DAC, supports up to 1GSPS sampling rate, and outputs up to 420M (MAX).

A large number of button capacitors are used for filtering on the board to achieve the best filtering effect, and AMS1117 is used as the power chip, which makes the power supply more stable.

The AD9910 is a direct digital synthesizer (DDS) with a built-in 14 BIT DAC that supports sampling rates up to 1GSPs. AD9910 adopts advanced DDS patent technology, can greatly reduce power consumption under the premise of not sacrificing performance.

The DDS/DAC combination forms a digitally programmable high-frequency analog output frequency synthesizer capable of generating frequency agile sinusoidal waveforms at frequencies up to 400 MHZ.

Users have access to three signal control parameters for controlling the DDS, including frequency, phase, and amplitude. The AD9910 utilizes a 32BIT accumulator to provide fast frequency hopping and frequency tuning resolution. At 1 GSPS sampling rate, the tuning resolution is ~0.23 HZ. The DDS also implements fast phase and amplitude switching.

The user can program the AD9910's internal control registers through the serial I/O port to control the AD9910. The AD9910 integrates static RAM and can support multiple combinations of frequency, phase, and/or amplitude modulation.

The AD9910 also supports user-defined numerically controlled digital ramp modes of operation. In this mode, frequency, phase or amplitude varies linearly with time.

The built-in high-speed parallel data input port of the AD9910 enables direct modulation of frequency, phase, amplitude, or pole to support more advanced modulation functions.

AD9910 operates over the extended industrial temperature range
