A good PCB layout for the MAX9206EAI+T involves keeping the input and output traces separate, using a solid ground plane, and placing the device close to the power supply. Additionally, using a shielded cable for the HDMI output can help reduce EMI.
To ensure proper power and decoupling, use a 1.8V power supply with a low impedance output, and decouple the device with 0.1uF and 10uF capacitors between VCC and GND. Place the capacitors close to the device and use a low-ESR capacitor for the 10uF decoupling capacitor.
The MAX9206EAI+T supports cable lengths up to 30 meters (100 feet) at 4K resolution and 60Hz refresh rate, and up to 15 meters (50 feet) at 8K resolution and 60Hz refresh rate, assuming a high-quality HDMI cable with proper shielding and termination.
The MAX9206EAI+T is configured for a specific HDMI version through the use of external resistors on the CFG0-2 pins. For example, to configure for HDMI 2.0, connect CFG0 to GND, CFG1 to VCC, and CFG2 to GND. Refer to the datasheet for specific configuration options.
The MAX9206EAI+T supports data rates up to 18Gbps, which is sufficient for 4K resolution at 60Hz refresh rate and 8K resolution at 30Hz refresh rate.
