Abstract
An interface in a communications system includes a physical layer transceiver (PHY) for coupling to a wireline channel medium, and for coupling to a functional device via a single-ended cable. The PHY is an integrated circuit (IC) device having first and second differential input/output (I/O) conductors for coupling to the functional device, an impedance element configured to terminate a first one of the differential I/O conductors to a system ground, a second one of the differential I/O conductors being coupled to the single-ended cable, and a common-mode filter coupled to both of the differential I/O conductors. The PHY may further include a printed circuit board (PCB), with the IC device being mounted on the PCB, the first and second differential I/O conductors being signal traces on the PCB. The single-ended cable may be a coaxial cable.
