Method for detecting a number of consecutive valid data frames and advancing into a lock mode to monitor synchronization patterns within a synchronization window

A signal receiver interface circuit, comprising:

• a data acquisition module receiving an input data bit stream pattern and providing at an output consecutive data frames;
• a synchronization module receiving the output of the data acquisition module in addition to reset and enable signals and outputting a data bit stream of consecutive frames;
• a synchronization detection, validation and alignment module receiving the output of the synchronization module and generating a plurality of channels of data;
• a controller receiving the plurality of channels of data, the controller outputs a plurality of consecutive frames of the input data bit stream;
• a wideband synchronization module receiving the input data bit stream output from the controller for synchronization on byte aligned synchronization patterns at the beginning of each wideband communications block frame, following the identification of the bit stream synchronization, the wideband frame synchronization module outputs the input data bit stream;
• a memory buffer module receiving the input data bit stream output from the wideband frame synchronization module where synchronization has been established for intermediate storing of a data bit stream for further processing;
• and
• a bus interface coupled to the memory buffer module for transferring the stored data bit stream for processing and analysis.

A method for identifying synchronization lock for consecutive data frames in a data bit stream, comprising:

• receiving frames of data in an input bit stream;
• detecting a predetermined number of consecutive data frames having a valid format in the input bit stream;
• and
• in response to detecting a predetermined number of consecutive valid format data frames, monitoring for synchronization patterns within a synchronization window, wherein when the predetermined number of consecutive data frames with corresponding valid formats is detected, advancement into a lock mode may occur to monitor one or more of the synchronization patterns within the synchronization window.
