ABSTRACT:
A method and apparatus is described herein for pulse shift modulation of output waveforms for reducing crosstalk on interconnects. Based on input pulses/bits, an output waveform is selectively delayed by a shift value to ensure transitions in a first direction occur in a first half of a period and transitions in a second direction occur in a second half of the period. When the same pulse shift modulation is implemented on surrounding traces, certain worst-case crosstalk scenarios are reduced; thus reducing crosstalk and increasing performance in power consumption and speed of data transfer.
