Abstract
Method and system for a high-speed multiplexer with reduced inter-symbol interference are disclosed. In one embodiment of the present invention, two input bit streams are interleaved by a multiplexer to derive an output bit stream. Each input bit stream is latched by a return-to-differential-zero latch that drives its input bit stream to a neutral state when it is not selected by the multiplexer as output. In an alternate embodiment of the present invention, a pre-selector receives two input signals, determines which of the two input signals will be selected as output of the multiplexer and passes the bit stream unaltered, while passing a differential zero value in place of the unselected input bit stream.
