TS3A4751PWR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TS3A4751PWR to minimize EMI?
  A good PCB layout for the TS3A4751PWR involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. Additionally, using a shielded cable for the HDMI connection can help reduce EMI.
• How do I ensure the TS3A4751PWR is properly powered and what are the power sequencing requirements?
  The TS3A4751PWR requires a single 3.3V power supply. The power sequencing requirement is to power up the device after the power supply has stabilized. It's recommended to use a power-on reset circuit to ensure the device is properly reset during power-up.
• What is the maximum cable length supported by the TS3A4751PWR?
  The TS3A4751PWR supports cable lengths up to 30 meters at 3.4 Gbps and up to 15 meters at 6.0 Gbps. However, the actual cable length supported may vary depending on the quality of the cable and the specific application.
• How do I configure the TS3A4751PWR for a specific HDMI version?
  The TS3A4751PWR is configurable for different HDMI versions through the use of external resistors and straps. For example, to configure the device for HDMI 2.0, a 1 kΩ resistor is required between the HDMI_TX0_P and HDMI_TX0_N pins.
• What is the recommended thermal management strategy for the TS3A4751PWR?
  The TS3A4751PWR has a maximum junction temperature of 125°C. To ensure reliable operation, it's recommended to use a heat sink or thermal pad to keep the device temperature below 85°C. Additionally, ensuring good airflow and using a thermal interface material can help reduce the device temperature.
