CH7105B-BFI Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from the power plane to minimize noise and EMI.
  • Use high-quality HDMI cables with good shielding and impedance control. Also, ensure that the cable is rated for the desired bandwidth (e.g., 4K@60Hz) and length. Consider using active HDMI cables or repeaters for longer distances.
  • The CH7105B-BFI supports cable lengths up to 30 meters (100 feet) at 4K@60Hz resolution. However, the actual cable length may vary depending on the cable quality, signal frequency, and system configuration.
  • MST mode is enabled by setting the MST_EN pin high. The device will then support up to 4 independent streams. Consult the datasheet and application notes for detailed configuration and programming information.
  • The power consumption of the CH7105B-BFI varies depending on the operating mode. In typical HDMI 2.0 mode, the power consumption is around 1.2W. In low-power mode, it can be as low as 0.5W. Consult the datasheet for detailed power consumption information.
