9 / 33 page  RTS5411 Realtek Semiconductor Corp. 6 V1.2 4.2 Pin Descriptions Pin Name Pin No. I/O Type Description Power supply DV33 4,22,48,73 Power 3.3V power supply for digital circuits DV12 3,49,50 Power 1.2V power supply for digital circuits AV12 7,13,19,25,31, 58,64,70 Power 1.2V power supply for analog circuits LDO_V5_IN 54 Power 5V to 3.3V LDO input. Short this pin to DV33, when on-chip LDO is not used. V33_OUT 55 Power 3.3V output (from internal 5V to 3.3V Low Dropout Regulator) Short this pin to DV33, when on-chip LDO is not used. SWR_V5_IN 53 Power 5V to 1.2V SWR input Connect this pin to LDO_V5_IN if internal switching regulator isn ’t used. SWR_GND 51 GND Reference GND for 1.2V SWR SWR_OUT 52 Power 5V to 1.2V SWR output Left this pin floating if internal switching regulator isn ’t used. GND 61 GND Reference ground E-PAD - GND The bottom of the package has a thermal pad. The pad shall be connected to the reference ground Analog Interface RREF 1 I Connect an external resistor (6.2K ±1%) to the Reference GND System Clock XTLI 74 I 12Mhz Crystal input. XTLO 75 O 12Mhz Crystal output. LED Control Pins GPIO0/SMBCL, GPIO2/SCL, GPIO4,GPIO6 32,34,36,38 I/O General Purpose I/O. Now used for LED application to indicate Downstream Ports transmit and receive activity .The LEDs will blink when there is USB transfer under corresponding port. These pins have weak internal pull up resistances. Left these pins floating when unused. The GPIO0 can be configured as a SMBus clock pin The GPIO2 can be configured as a I2C clock pin GPIO1/SMBDA, GPIO3/SDA, GPIO5,GPIO7 33,35,37,39 I/O General Purpose I/O. Now used for LED application to indicate Downstream Ports over-current condition. The LEDs will on when over-current condition is detected. These pins have weak internal pull up resistances. Left these pins floating when unused. The GPIO1 can be configured as a SMBus data pin The GPIO3 can be configured as a I2C data pin |
