Power (VDD): These pins are connected to the 3.3V power supply to power the chip. Ground (GND): The ground pins are the reference point for the entire device. USB Data Pins (USBD- and USBD+): These pins are used for USB data communication. These pins transfer information between the device and the USB host. Reset Pin (RST): This pin is used to reset the device when driven low. LED Pins (LED0, LED1): These pins indicate the link status and activity (e.g., blinking when data is transmitted). MII Pins (MIIMDIO, MIIMDC, MIIRXD0-3, MIITXD0-3): These pins are for managing and controlling the Ethernet link using the MII interface . They handle data transmission and reception. PHY_LINK Pin: This indicates the status of the physical Ethernet link (High for Link-up, Low for Link-down). Clock Pins (TXCLK, RXCLK): These provide the clock signals necessary for Ethernet communication. RX and TX Data Pins (RXD, TXD): These pins are used for data transmission and reception in Ethernet communication. Error Pins (RXER, CRSDV): These pins indicate errors or data validation during communication.FAQ for RTL8152B-VB-CG
