Instructions for Use:

1. Power Supply Connection:

   • Connect the power supply pin (VDD) to a stable 3.3V supply.
   • Ensure the ground (GND) is properly connected to maintain signal integrity.

2. HDMI Connections:

   • Connect the HDMI input and output ports according to the datasheet pin configuration.
   • Verify that all differential pairs are correctly routed to minimize crosstalk and interference.

3. Configuration:

   • Use the I2C interface to configure the device settings as required.
   • Refer to the command set in the datasheet for detailed configuration options.

4. HDCP Authentication:

   • Ensure that both the source and sink devices support HDCP 1.4 for proper authentication.
   • Follow the HDCP protocol guidelines for key management and data encryption.

5. CEC Setup:

   • Configure CEC functions through the I2C interface if needed.
   • Implement any custom CEC commands or default operations as per application requirements.

6. Testing:

   • Perform initial testing with known good HDMI sources and sinks.
   • Validate signal integrity and timing compliance using appropriate test equipment.

7. Layout Considerations:

   • Place decoupling capacitors close to the power supply pins.
   • Maintain short and direct routing for high-speed signals to avoid signal degradation.

For detailed specifications and advanced configurations, refer to the full datasheet provided by the manufacturer.
