differential signaling |
Also found in: Wikipedia | 0.07 sec. |
differential signalingUsing two wires for each electrical path for high immunity to noise and crosstalk. The signals are sent down one wire as positive and the other as negative, and the circuit at the receiving end derives the signal from the difference between the two. It is superior to single-ended signaling, where the reference voltage is ground and can vary over long distances. In differential signaling, the reference voltage is controlled. Typically, twisted pairs are used so that external radiation impacts both wires at the same place, and the noise can be detected more easily. See SCSI. How to thank TFD for its existence?

Maggs said: "In RedMere, we have identified a ground-breaking communications technology for differential signalling systems, with applications in storage, consumer and PC markets. The I/O technology also features a double data rate (DDR) memory interface and 1Gbps low-voltage differential signalling (LVDS). Fully compatible with the ISO 11898-2 standard, the AMIS-30663 provides differential signalling capability to the CAN bus via the transmit and receive pins of the CAN controller. |
