CH7026B-TF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital signal traces separate, and use a common mode filter to reduce EMI.
  • Use shielded cables with a characteristic impedance of 100 ohms, and ensure the cable length is within the recommended maximum of 10 meters. Also, use a common mode filter and a shielded connector to reduce EMI.
  • The CH7026B-TF can operate from -40°C to 85°C, but the recommended operating temperature range is 0°C to 70°C for optimal performance and reliability.
  • Configure the CH7026B-TF in TMDS mode, and set the transmission rate to 6 Gbps. Ensure the HDMI 2.0 transmitter is enabled, and the clock frequency is set to 100 MHz.
  • Power up the device in the following sequence: VCC, then AVCC, and finally DVCC. Ensure the power supply voltage is stable and within the recommended range before applying the clock signal.
