| description | A transceiver having shared and discrete components forming a transmit path and a receive path configured to couple to a communication medium for establishing a multi-tone modulated communication channel thereon. The transceiver includes a line driver component on the transmit path. The line driver is configured to respond to a protocol determination and by configuring at least one of a transmit power level and a transmit bandwidth of the multi-tone modulated communication channel on the communication medium. The line driver includes a plurality of pre-amplifiers each exhibiting a combination of transmit power and bandwidth for amplification of a transmit signal modulated with a selected multi-tone modulation protocol. The line driver also includes a single output amplifier having an output coupled to the communication medium and an input switchably coupled to an output of a selected one of the plurality of pre-amplifiers in response to the protocol determination. |
