Abstract
A transfer strobe delay stage selector insures accurate transfer of data from high speed circuitry to low speed circuitry through use of a delay stage module comprising a plurality of delay stages, and an associated multiplexor for selecting one of the delay stages so as to provide accurate reception of parallel data by the low speed circuitry from the high speed circuitry. The transfer strobe delay stage selector incorporates a synchronization channel identification module for detecting synchronization channel information in the frames of data transferred from the high speed circuitry to the low speed circuitry and also includes control circuitry for adjusting the selected delay stage until synchronization channel identification is detected. A second embodiment of the invention provides an auxiliary synchronization channel identification module and associated control circuitry to dynamically adjust the selected delay stage when variation in the propagation delay between the high speed and low speed circuitry occurs.
