An integrated apparatus for signal transmission and method therefor. The integrated apparatus for signal transmission is adaptable to different data transfer rates and includes an Ethernet controller and a fast-Ethernet controller, a decoding device, and a current source module. The Ethernet controller can used for receiving a 10TXD signal and producing an adjustment signal by sampling the received 10TXD signal. The fast-Ethernet controller is used for receiving a 100TXD signal and a 100TXDN signal and producing an adjustment signal by sampling the received 100TXD and 100TXDN signal. In addition, the decoding device, according to a selection signal, is used to determine the data transfer rate and select one adjustment signal from the adjustment signals from the Ethernet and fast-Ethernet controllers. The selected adjustment signal is then fed into a current source module and an amplifier. The current source module supplies the amplifier with an operating current based on the selected adjustment signal, thereby producing either an approximation to a 10 Base-T signal or a 100 Base-T signal.
