Abstract

See full text

Methods, apparatus and systems for de-correlating training pattern sequences for high-speed links and interconnects. The high-speed links and interconnects employs multiple lanes in each direction for transmitting and receiving data, and may be physically implemented via signal paths in an inter-plane board such as a backplane or mid-plane, or via a cable. During link training, a training pattern comprising a pseudo random bit sequence (PBRS) is sent over each lane. The PBRS for each lane is generated by a PBRS generator based on a PRBS polynomial that is unique to that lane. Since each lane employs a different PRBS polynomial, the training patterns between lanes are substantially de-correlated. Link negotiation may be performed between link endpoints to ensure that the PBRS polynomials used for all of the lanes in the high-speed link or interconnect are unique. Exemplary uses include Ethernet links, Infiniband links, and multi-lane serial interconnects.
