MAX3390EEUD+T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX3390EEUD+T to minimize EMI and noise?
  A good PCB layout practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the signal traces short and away from noise sources. Additionally, use a common-mode filter or a ferrite bead to filter out high-frequency noise.
• How do I ensure the MAX3390EEUD+T is properly powered and decoupled?
  Use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) as close as possible to the VCC pin, and add a 1uF capacitor in parallel to filter out high-frequency noise. Ensure the power supply is stable and within the recommended voltage range (1.7V to 3.6V).
• What is the maximum data rate that can be achieved with the MAX3390EEUD+T?
  The MAX3390EEUD+T can support data rates up to 100Mbps, but the actual data rate depends on the specific application, cable length, and noise environment. For high-speed applications, use a shielded cable and ensure proper termination to minimize signal reflections.
• How do I handle hot-swapping or hot-plugging with the MAX3390EEUD+T?
  To prevent damage from hot-swapping or hot-plugging, use a current-limiting resistor or a power switch with overcurrent protection. Additionally, ensure the device is powered down before disconnecting or connecting the USB cable.
• What are the thermal considerations for the MAX3390EEUD+T?
  The MAX3390EEUD+T has a maximum junction temperature of 150°C. Ensure good airflow, use a heat sink if necessary, and avoid blocking airflow around the device. Monitor the device temperature and adjust the thermal design accordingly.
