Item description: signal Generator sine / rectangle DDS AD9850 40MHz
The module can generate the following signals: 2 x sine, 2 x rectangular with frequency up to 40 MHz. The system communicates via a serial bus, or by sending the bits in parallel. The maximum frequency of the generated signal is 40 MHz, the command word consists of 32 bits. It is supplied with the voltage of 3.3 V or 5 V.

| Pin | Description |
|---|---|
| VCC |
Supply voltage from 3.3 V to 5 V. |
| GND | Module's ground |
| W_CLK | The clock signal of the communication bus. |
| FQ_UD | Changing the frequency, if a rising edge appears on this pin, the system will update the frequency to the value specified in the input register. |
| DATE | The data line of the serial interface. |
| RESET | Reset the module, a high signal removes the data from all registers of the system. |
| D0-D7 | 8-bit bus parallel: D0=LSD, D7=MSB. |
| ZOUT1 | The output signal of the sine signal No. 1. |
| ZOUT2 | The output signal of the sine signal No. 2. |
| QOUT1 | The output of the rectangular signal No. 1. |
| QOUT2 | The output of the rectangular signal No. 2. |
| Potentiometer | Used to adjust the fill of the rectangular signal. |
