APPLICATION NOTE 302
DS2141, DS21Q41, DS21Q43 8-MHz System Clock Operation

Abstract: The application note describes how to design a backplane of 8.192MHz that simultaneously connects
to any four framers of the following: DS21Q41 quad T1 framer, DS21Q43 E1 framer, DS2141 T1 controller,
DS2151 T1 single chip transceiver (SCT), and DS2153 E1 SCT.


The DS2141, DS21Q41, DS21Q43, DS2151and DS2153 PCM signals can interface to an 8 MHz system
backplane. Typically this application is used to multiplex four 2.048 MHz PCM streams onto a single 8 MHz PCM
stream. To accomplish this the elastic stores are enabled and pl
