Abstract: | This paper describes a new kind of PCM decommutator that includes the programmable bit synchronizer and frame synchronizer. The decommutator is all digitalized and uses architecture of PC plug-in card. The card is capable of handling 8 kinds of standard IRIG codes. EPLDs are used for the realization of the digital logic sections. Bit synchronizer can handle data upto 1 Mbps (NRZL), frame synchronizer is designed to work upto 10 Mbps. |
