Abstract:
1. A method of capturing data from a data bit stream, comprising the steps of: from said data bit stream, generating, with a sampler system, successive bit sample sequences that each comprise N interleaved bit sample phases, wherein N is an integer; in said bit sample sequences, identifying, with a data capturer, subsampling strings formed of less than N consecutive bit samples with the same bit sample value; with said data capturer, invalidating the bit sample phase of any bit sample that adjoins said strings; and with said data capturer, forming data with successive bit sample phases that remain valid after said invalidating step; wherein said identifying step includes the steps of: with a data analyzer, identifying transitions from one bit sample value to a different bit sample value; and with a decision processor, identifying valid bit sample phases in response to said subsampling strings and said transitions; and wherein said forming step includes the steps of: diverting and delaying a copy of said bit sample sequences along a delay path of a delay circuit to facilitate said identifying and invalidating steps; and with a multiplexer that responds to said decision processor, subsequently extracting a valid bit sample phase from said delay path to thereby form said data.
