Programozási soros interfész modul chip AD9833 szinuszos jelgenerátor DDS modul GY-9833
Programming serial interface module chip AD9833 sine wave signal generator DDS module GY-9833
illustrate:
AD9833 is a low-power, programmable, sine wave generator, triangle wave and square wave output. It needs to be generated in various types of waveform detection, implementation and time domain reflectometry (TDR) applications. The output frequency and phase are all programmable software, which can be easily adjusted. No external components are necessary. The frequency register is 28 bits wide: the clock frequency is 25 MHz, which can achieve a resolution of 0.1 Hz; the clock frequency of AD9833 is 1 MHz, which can be tuned to a resolution of 0.004 Hz
AD9833 has a standard serial interface, allowing the device to be directly connected to different microprocessors. The device uses an external serial clock to write data or information to the control device
The AD9833WBRMZ-REEL model can be controlled to meet the quality and reliability requirements of automotive applications. Please note that the car specifications of this model may be different from the commercial model; therefore, the designer must carefully read the specific part of this data sheet. Only automotive grade indicating products can be used in automotive applications. Please contact your local ADI company representative account to learn about specific product ordering information and obtain specific car reliability reports for these models
AD9833 writes through the serial interface line. The operating clock frequency of this serial interface is up to 40 MHz, and the standard is compatible with DSP and microcontroller. The device is powered by a 2.3 V 5.5 V power supply
AD9833 has a power-down function (SLEEP). This can turn off the unused parts of the device, thereby minimizing the power consumption, for example, the DAC can be turned off when the output clock is generated
