Patent attributes
A system and method are provided to detect an extended error burst in a data interface. An original error burst has a given length prior to or during transmission. Data transmission processing can extend the original error burst beyond its original length to become an extended error burst with an effective length greater than the original error burst length. Such data transmission processing can include: de-interleaving data on a multi-lane data interface; feedback from a Decision Feedback Equalizer (DFE) receiver; and/or block line decoding, such as 8B/10B block line code decoding. An extended error burst detector can include a suitable error detecting code, such as an r-bit cyclic redundancy check (CRC) code developed in relation to known extended error burst patterns, to detect all extended error bursts based on an up to r-bit original error burst. The detector can also detect error bursts that are not extended beyond the original error burst length.
