T1/E1/J1 Single Chip Transceiver with Wide Dynamic Range LIU

Product Detail

The MT9074 is a single chip device, operable in either T1 or E1 mode, integrating either an advanced T1 (T1 mode) or PCM 30 (E1 mode) framer with a Line Interface Unit (LIU). The framer interfaces to a 2.048 Mbps backplane providing selectable data link access with optional HDLC controllers for either the FDL bits and channel 24 (T1 mode) or Sa bits and channel 16 (E1 mode). The LIU interfaces the framer to T1 (T1 mode) or PCM 30 (E1 mode) transformer-isolated four-wire line with minimal external components required.
