MT9074
MT9074 is T1/E1/J1 Single Chip Transceiver manufactured by Zarlink Semiconductor.
Features
- bined E1 (PCM30) 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 30 d B (5000 ft. of 24 AWG cable) In E1 mode the LIU can recover signals attenuated by up to 30 d B (1900 m. of 0.65 mm 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 2.048 Mbit/s backplane bus for both data and signaling Japan Tele J1 Framing and Yellow Alarm
