摘要：MAX3831多路复用器(mux)及解复用器(分接）有一通道分配功能，使它能够适当地将产出分配给正确的渠道。当启用此功能只适用装裱SDH/SONET数据信号。此设计备注讨论如何禁用该信道分配功能，对于这些应用程序在用户想要执行下游的频道分配或非SDH/SONET应用程序。ApplicationNote:HFDN-1.0Rev.1;04/08DisablingtheChannel-AssignmentFeatureoftheMAX3831MaximIntegratedProductsDisablingtheChannel-AssignmentFeatureoftheMAX3831I.OverviewSDH/SONETheaders.TheMAX3831invertschannel4atthemultiplexerandtheninvertschannel4againTheMAX3831Mux/Demuxhasachannelassignmentatthedemultiplexer.Ifthechannelsareproperlyfeaturethatallowsittoproperlyassigntheout……
