Abstract
A data bit synchronizer particularly adapted for use with a multiplexing character processor of the type that multiplexes data characters to and from a plurality of communication lines to a central processing unit. The data bit synchronizer is operable with communication lines carrying various protocols and data bit rates. A RAM memory stores the control and status information for each of the plurality of communication lines. The RAM is accessed at a rate corresponding to the rate used to multiplex the communication lines to repeatedly output the information associated with each communication line. The data bit synchronizer also incorporates a bit rate clock generator for generating timing signals corresponding to selectable output data rates. A multiplexer is used to multiplex the timing signals with the control and status information.
