DVI RECEIVER FOR DETECTING DATA BOUNDARY AND RESTORING DATA ENABLE SIGNAL IN DATA RECEIVED FORM DVI AND METHOD THEREFOR

摘要

A DVI receiver and method are disclosed that can detect data boundaries and recover data enable signals from data received from a digital video interface. A digital visual interface (DVI) receiver according to an embodiment of the present invention receives serialized data transmitted by DVI to generate parallel data and a data enable signal transmitted from a DVI transmitter, and a data alignment unit, boundary and enable signal. And a signal generator and a data selector. The data alignment unit generates a detection input signal including a data signal sampling the received data n times, current data shifted n times, next data shifted n times, and next data shifted nn-2 times. do. A boundary and enable signal generator generates and synchronizes the first partial signal of the current data and the previous data and the second partial signal of the previous data and the previous data to generate synchronization information. In response to generating a data boundary, and the data enable signal. A data selector generates the parallel data in response to the data boundary and the detection input signal. The DVI receiver according to the present invention has an advantage that it is possible to eliminate an error in detecting the synchronization information signal that may be generated in the data combination.; DVI, Data Boundary, Data Enable Signals
