ABSTRACT:
A transmission system for transmitting a signal from a host to a transmission medium is disclosed. The transmission system includes a current-mode digital-analog converter, an on-chip low-pass filter, a line driver, and output impedance control. Further, a method for transmitting a signal from a host to a transmission medium using on-chip filtering is disclosed. The transmission system and method can be used in transmission of Ethernet signals onto an unshielded twisted pair cable. In addition, with appropriate modification, the transmission system and method can be used for transmitting ATM or other signals onto a transmission medium.
