The recommended operating temperature range for the RTL8139D-LF is 0°C to 70°C (commercial temperature range) and -40°C to 85°C (industrial temperature range).
The RTL8139D-LF can be configured for half-duplex or full-duplex operation through the DUPLEX_MODE pin. A high level on this pin enables full-duplex operation, while a low level enables half-duplex operation.
The RTL8139D-LF supports a maximum cable length of 100 meters, which is the standard Ethernet cable length.
Flow control can be implemented using the RTL8139D-LF's built-in flow control mechanism, which uses the TX_FLOW_CTRL and RX_FLOW_CTRL pins to control the flow of data transmission and reception.
The power consumption of the RTL8139D-LF is typically around 350mA in active mode and 100mA in power-down mode.
