Instructions for Use

1. Power Supply:

   • Connect the VDD pin to a stable power supply within the range of 2.7V to 5.25V.
   • Ensure that the power supply is clean and stable to avoid noise in the audio signal.

2. Analog Inputs:

   • Connect the analog audio signals to the IN1P, IN1N, IN2P, and IN2N pins.
   • Use differential inputs for better noise rejection.

3. Digital Interface:

   • Connect the I2S interface pins (BCLK, LRCLK, SDOUT) to your microcontroller or DSP.
   • Configure the I2S interface settings (e.g., clock rate, data format) according to your system requirements.

4. Grounding:

   • Ensure a good ground connection to minimize noise and interference.
   • Use a star grounding technique if multiple components are involved.

5. Decoupling Capacitors:

   • Place decoupling capacitors (typically 0.1μF and 10μF) close to the VDD pin to filter out high-frequency noise.

6. Configuration:

   • Use the control register to configure the ADC settings such as gain, input selection, and digital interface parameters.
   • Refer to the datasheet for detailed register maps and configuration guidelines.

7. Testing:

   • After setup, test the ADC by inputting a known audio signal and verifying the digital output using a logic analyzer or similar tool.
   • Check for any noise or distortion and adjust the circuit as necessary.

8. Handling:

   • Handle the CS5351-KSZ with care to avoid static damage.
   • Follow standard ESD precautions when handling and soldering the component.

For more detailed information, refer to the CS5351-KSZ datasheet provided by the manufacturer.
