This DDS (direct digital synthesis) module generates sine wave and square waves based on the 40-bit (5 byte) value that is written to the register. By means of a serial or parallel connection, this module can, as it were, be programmed to generate signals with the correct wavelength and amplitude. The module can simultaneously generate 2 sine wave (max 40 MHz) and 2 block waves (max 1 MHz). With an input voltage of 5V and a current of up to 270mA, this sign can be powered.
Word Load Clock. This clock signal is used to write bits to the register
Frequency Update. When this signal becomes high, the register is read out and the pointer is reset to 0 for writing data
