Transfer strobe time delay selector and method

摘要

A transfer strobe delay stage selector insures accurate transfer of data from high speed circuitry (25) to low speed circuitry (27) through use of a delay stage module (34) comprising a plurality of delay stages (36), and an associated multiplexor (38) for selecting one of the delay stages so as to provide accurate reception of parallel data by the low speed circuitry (27) from the high speed circuitry (25). The transfer strobe delay stage selector incorporates a synchronization channel identification module (42) for detecting synchronizsation channel information in the frames of data transferred from the high speed circuitry (25) to the low speed circuitry (27) and also includes control circuitry (52) for adjusting the selected delay stage until synchronization channel identification (42) is detected.
