ABSTRACT:
A method for synchronizing interconnects in a link system according to various embodiments can include receiving input data at a transmit side, the transmit side including at least one pseudo-random bit sequence scrambler; scrambling the input data at the transmit side via the pseudo-random bit scrambler with dual tap sequences resulting in scrambled data; transmitting the scrambled data with the dual tap sequences along all lanes of a plurality of lanes to a receive side via a bus interconnecting the plurality of lanes, the receive side including at least one pseudo-random bit sequence descrambler; synchronizing the at least one pseudo-random bit sequence scrambler to the at least one pseudo-random bit sequence descrambler; using an edge detection or transition detection device for synchronization of the descrambler to the scrambler; and de-scrambling the transmitted scrambled data at the receive side resulting in the input data.
