Overview

MT9074 T1/E1/J1 Single Chip Transceiver Advance Information Features • Combined E1 (PCM 30) and T1 (D4/ESF) framer, Line Interface Unit (LIU) and link controller with optional digital framer only mode In T1 mode the LIU can recover signals attenuated by up to 36 dB (6000 ft.
of 24 AWG cable) In E1 mode the LIU can recover signals attenuated by up to 36 dB (2000 m.
of 0.
65mm cable) Two HDLCs: FDL and channel 24 in T1 mode, timeslot 0 (Sa bits) and timeslot 16 in E1 mode Two-frame elastic buffer in Rx & Tx (T1) directions Programmable transmit delay through transmit slip buffer Low jitter DPLL for clock generation Enhanced alarms, performance monitoring and error insertion functions Intel or Motorola non-multiplexed parallel microprocessor interface ST-BUS 2.

The framer interfaces to a 2.
048 Mbit/s 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.
In T1 mode the MT9074 supports D4, ESF and SLC96 formats, meeting the latest recommendations including ITU I.
