Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the specified range of 2.7V to 5.5V.
   • Connect a decoupling capacitor (0.1μF) close to the power supply pins to reduce noise.

2. Input Signals:

   • The differential input voltage range should be between -1V and +1V.
   • Ensure the input signals are properly terminated to avoid reflections and signal degradation.

3. Output Configuration:

   • The output voltage swing is differential and should be within -0.5V to +0.5V.
   • Use appropriate load resistors to match the output impedance of the device.

4. Clocking:

   • The clock frequency range supported is from 32kHz to 192kHz.
   • Ensure the clock signal is stable and has minimal jitter to maintain performance.

5. Temperature Considerations:

   • The operating temperature range is -40°C to 85°C.
   • Store the device in temperatures ranging from -65°C to 150°C to ensure longevity.

6. Signal Quality:

   • Monitor the signal-to-noise ratio (SNR) and total harmonic distortion (THD) to ensure high-quality audio performance.
   • Channel separation should be maintained at 100dB for optimal performance.

7. Jitter Management:

   • The device can tolerate up to 10ps of jitter in the clock signal.
   • Use low-jitter clock sources and proper PCB layout techniques to minimize jitter.

8. Installation and Handling:

   • Handle the device with care to avoid static damage.
   • Follow standard ESD precautions during installation and handling.

9. Testing and Verification:

   • After installation, verify all connections and parameters to ensure the device is functioning correctly.
   • Use test signals to validate the performance of the device.
