AD9852ASTZ Typical application Circuitry

AD9852ASTZ

AD9852ASTZ is a high-performance Direct Digital Synthesis (DDS) chip produced by Analog Devices. It is designed to generate sine and triangular waves, with applications in frequency synthesis, test and measurement equipment, and communication systems.

The key parameters and features of AD9852ASTZ include:

1. Clock speed: up to 300 MHz

2. Output frequency range: DC to 180 MHz

3. Resolution: 14 bits

4. Operating temperature range: -40°C to +85°C

For this article, let's consider the application scenario of generating a sine wave output for a frequency synthesizer. Here are the detailed steps on how to connect the AD9852ASTZ for this application:

1. Power Supply:

- Connect VDD (pin 12) to a 5V supply, and connect GND (pin 14) to ground.

2. Clock Input:

- Connect a clock source to REF CLK IN (pin 15). The DDS's output frequency is set by the frequency of this clock source.

3. Digital Control Inputs:

- Attach pin 11 of RESET to a microcontroller digital output pin. This pin is used to reset the DDS.

- Attach pin 10 (I/O UPDATE) to a different pin on your microcontroller that is used for digital output. This pin is used to update the DDS's output frequency.

- Attach pin 9 (WORD LOAD) to a different pin on your microcontroller used for digital output. This pin is used to load the frequency tuning word.

4. Output:

- Connect the output pin, DAC OUT (pin 6), to your circuit where you need the sine wave signal.

When designing the circuit, consider the following:

1. Ensure that the supply voltage and clock frequency are within the specified range for the AD9852ASTZ.

2. Make sure that the microcontroller's digital output pins are compatible with the DDS's digital input pins.

3. Take into account the impedance of the circuit where you are connecting the output of the DDS, as this may affect the quality of the sine wave signal.

4. If you need to generate a precise frequency, use a crystal oscillator as the clock source for the DDS.

By following these guidelines, you should be able to successfully use the AD9852ASTZ to generate a sine wave output for your frequency synthesizer application.
