Abstract
An improved transmission protocol is used to transmit a signal between two components of an electronic device. The improved transmission protocol is configured to reduce the number of simultaneous channel transitions that occur when multiple signal channels are transmitted in parallel. Reducing the number of simultaneous channel transitions is beneficial because a signal that is subject to skew, distortion, or electromagnetic interference during transmission may have a shorter settling time when fewer channels undergo a transition simultaneously. When the protocol is used to transmit a signal from a controller to an optical pickup unit in an optical data storage system, the reduced settling times allow for a higher data transmission rate.
