Circuit and method for twisted pair current source driver

摘要: A mechanism and method for efficiently communicating information regarding particular communication rate ("speed signal") between two or more stations (of a network). The transmitter operates on the IEEE P1394 High Performance Serial Bus to supply both differential common mode signaling required by standard exemplary data transfer rates of 100 200 Mbit transmission. present invention includes transmission circuit that may operate in signal simultaneously utilizing twisted pair cable. Data be transmitted at small signals. Information speed coupled units using variations voltage over pair. Communication initiated slower then upgraded as appropriate units. allows an efficient single transmit also use high with voltage. is especially useful within networks having varying versions rates.
