Abstract
A transceiver includes upstream differential signal lines DPUP and DMUP, downstream differential signal lines DPDW and DMDW, common differential signal lines DPCM and DMCM, a first transmission driver of which outputs are connected to DPUP and DMUP, a second transmission driver of which outputs are connected to DPDW and DMDW, a first switch circuit which connects the first transmission driver to a logic circuit during upstream connection and connects the second transmission driver to the logic circuit during downstream connection, a second switch circuit which respectively connects DPUP and DMUP to DPCM and DMCM during the upstream connection and respectively connects DPDW and DMDW to DPCM and DMCM during the downstream connection, and a third transmission driver connected to DPCM and DMCM.
