Efficient N-factorial differential signaling termination network
摘要:
A termination network circuit for a differential signal transmitter comprises a plurality of n resistance elements and a plurality of differential signal drivers. A first end of each of the resistance elements is coupled at a common node, where n is an integer value and is the number of conductors used to transmit a plurality of differential signals. Each differential signal driver may include a positive terminal driver and a negative terminal driver. The positive terminal driver is coupled to a second end of a first resistance element while the negative terminal driver is coupled to a second end of a second resistance element. The positive terminal driver and the negative terminal driver are separately and independently switchable to provide a current having a magnitude and direction. During a transmission cycle each of the resistance elements has a current of a different magnitude and/or direction than the other resistance elements.
