There is a package called 64-VFQFN Exposed Pad that contains it, and you can find it there. It's packaged in the shape of a Tray. It is important to regulate the temperature to -40°C~85°C in order to ensure reliable operation. It should be able to operate on a 1.8V~3.3VV power supply. There are terminations of type 64 in it. Providing a voltage of 1.2V leads to high efficiency. There are two LAN9353s in the number. In order for the device to function, 64 pins must be used.
