A good PCB layout is crucial for the TDA9950TT/C3,512. Ensure a solid ground plane, keep analog and digital signals separate, and use a star-configuration for power supply connections. Refer to NXP's application note AN11524 for more details.
To configure the TDA9950TT/C3,512 for HDMI 2.0 compliance, set the device to 'HDMI 2.0 mode' by writing 0x01 to register 0x10. Additionally, ensure the correct clock settings and configure the TMDS encoder according to the HDMI 2.0 specification.
The TDA9950TT/C3,512 supports cable lengths up to 30 meters at 6 Gbps, but this can vary depending on the cable quality, signal integrity, and system design. It's recommended to perform signal integrity analysis and testing to determine the maximum cable length for your specific application.
To troubleshoot HDMI signal integrity issues, use an oscilloscope to measure the eye diagram, jitter, and signal amplitude. Check for signal attenuation, reflections, and crosstalk. Ensure proper termination, and verify that the HDMI transmitter and receiver are properly configured. Refer to NXP's application note AN11525 for more troubleshooting tips.
The power consumption of the TDA9950TT/C3,512 depends on the operating mode and frequency. In typical HDMI 2.0 mode, the device consumes around 350-400 mW. However, this can vary depending on the system design and usage. Refer to the datasheet for more detailed power consumption information.
