THVD1451DRBT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-speed signals away from the power plane and use a 50-ohm transmission line for the HDMI signals.
  • Use a signal integrity analysis tool to simulate the signal transmission. Ensure the PCB trace impedance is matched to the device's output impedance (50 ohms). Use a common mode filter or a ferrite bead to reduce EMI.
  • The maximum cable length supported is 30 meters (100 feet) at 10.2 Gbps. However, this may vary depending on the cable quality, signal frequency, and system noise.
  • The device is configured through the I2C interface. Use the I2C bus to set the device registers according to the desired HDMI version (e.g., HDMI 1.4, HDMI 2.0, or HDMI 2.1). Refer to the datasheet for register settings.
  • The typical power consumption is 1.2 W (400 mA at 3.3 V) when transmitting at 10.2 Gbps. However, this may vary depending on the system configuration and operating conditions.
