AD9915BCPZ Typical application Circuitry

AD9915BCPZ

Analog Devices, Inc. developed the AD9915BCPZ, a direct digital synthesizer (DDS) integrated circuit. It is capable of generating high-frequency, programmable sine waves, which are useful in various applications, including communications, medical imaging, and test and measurement equipment.

The AD9915BCPZ has the following key parameters:

- Maximum clock frequency: 2.5 GHz

- False free dynamic range (SFDR) at 1 GHz: 70 dBc

- Resolution: 14-bit phase and 14-bit frequency

- Output frequency range: DC to 1.2 GHz

- Power supply: 1.8 V and 3.3 V

For example, consider an application where AD9915BCPZ is used as a signal generator in a communication system to modulate a carrier wave. Here is how you can connect the IC for this application:

1. Power Supply Connection:

Connect the AVDD (pin 70) and DVDD (pin 72) pins of AD9915BCPZ to a 1.8 V power supply. Connect the AVDD_IO (pin 68) pin to a 3.3 V power supply. It is necessary to connect pins 71 and 73, respectively, to ground and AGND and DGND.

2. Clock Input:

Connect an external clock source to the REFCLK (pin 48) pin of AD9915BCPZ. The frequency of the clock should be within the operating range of 0 to 2.5 GHz.

3. Digital Input:

Connect a microcontroller or FPGA to the SDIO (pin 37), SCLK (pin 35), and CS (pin 36) pins of AD9915BCPZ for digital control of the frequency and phase of the sine wave.

4. Output Connection:

Connect the IOUT (pin 32) pin of AD9915BCPZ to the input of the communication system's modulator.

When designing the circuit, some considerations should be taken into account:

- Ensure the power supply voltages are within the specified range to avoid damaging the AD9915BCPZ.

- The clock frequency should be within the operating range of 0 to 2.5 GHz.

- Properly time the digital input signals to ensure accurate frequency and phase modulation.

- Filter the output to remove unwanted harmonics and noise.

In summary, the AD9915BCPZ is a versatile DDS IC capable of generating high-frequency, programmable sine waves for various applications. The example provided illustrates how AD9915BCPZ can be used in a communication system to modulate a carrier wave. When designing the circuit, careful attention must be paid to the power supply voltages, clock frequency, digital input signal timing, and output filtering to ensure the correct operation of the IC.
