Instructions for AD9244BSTZ-40

1. Power Supply Configuration:

   • Connect AVDD and DVDD to appropriate power supplies as specified in the table.
   • Ensure stable decoupling capacitors are placed close to the power pins.

2. Input Signal Connection:

   • Connect the analog input signal to the differential input pins.
   • Ensure the input signal does not exceed the full-scale differential input range.

3. Clock Input:

   • Provide a clean clock signal to the CLK pin to achieve the desired sampling rate.
   • The maximum frequency should not exceed the maximum output data rate.

4. Data Output:

   • Configure the digital outputs according to your system's requirements.
   • Ensure that the digital interface is properly synchronized with the ADC’s output data rate.

5. Grounding and Layout Considerations:

   • Use a ground plane to minimize noise and improve performance.
   • Keep analog and digital grounds separate until they meet at a single point to avoid ground loops.

6. Testing and Evaluation:

   • Use an evaluation board or similar setup to test the ADC under various conditions.
   • Monitor SNR and SFDR to ensure the ADC is operating within expected parameters.
