A good PCB layout for the MAX3748HETE#TG16 involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing decoupling capacitors close to the device. Additionally, it's recommended to use a shielded cable for the USB interface to minimize EMI.
The MAX3748HETE#TG16 requires a single 3.3V power supply. It's recommended to power the device using a low-dropout linear regulator or a switching regulator with a low noise output. The power sequencing requirement is to power up the 3.3V supply before the USB interface is activated.
The MAX3748HETE#TG16 has a thermal pad that must be connected to a solid ground plane to dissipate heat. It's recommended to use a thermal interface material between the device and the PCB to improve heat transfer. Additionally, ensure good airflow around the device and avoid blocking the airflow with nearby components.
The MAX3748HETE#TG16 is a USB 3.0 hub controller, but it can also support USB 2.0 devices. To configure the device for USB 2.0, set the USB2EN pin high and the USB3EN pin low. For USB 3.0, set the USB2EN pin low and the USB3EN pin high.
The MAX3748HETE#TG16 has built-in ESD protection, but it's still recommended to take precautions to prevent ESD damage. Use ESD-safe handling and storage procedures, and consider adding external ESD protection devices, such as TVS diodes, to the USB interface.
