APPLICATION NOTE 353
General network interface design criteria for the DS2151 and DS2152


Abstract: This application note presents the basic network interface design criteria for a T1 transceiver. The transmit and receive
circuits for 5V and 3.3V devices are discussed.

Figure 1 illustrates a general form of the interface circuit for T1 transceiver chips. Not all of the components are necessary in all
applications. This circuit is used to illustrate how to distribute resistance around the transformers. Application note 324 discusses
