Initialization system for recovering bits and group of bits from a communications channel |
摘要 |
A system normally converts a parallel data word to a single serial data stream to use a high speed serial link. The parallel data word is partitioned into N sub-sets or nibbles and each nibble is then serialized and transmitted over N serial links using high speed differential drivers. Each of the N serialized nibbles are received in a differential receiver. The serialized nibbles are then coverted back into N parallel nibbles and the N parallel nibbles are then assembled back to the original parallel data word. To increase reliability, the received data is coupled to a tapped delay element having M stages of delay. A training sequence and algorithm are used to determine which of the taps of the delay element are a desired delay distance away from data transitions. These taps are then used to sample the incoming signals to reconstruct the parallel data word.
