Description

The MT90733 DS3 Framer (DS3F) is designed for mapping broadband payloads into the DS3 frame format, which meets ANSI’s T1.107-1988 and supplement T1.107a-1990.

Features

• DS3 payload access in either bit-serial or nibble-parallel mode

• C-bit parity or M13 operating mode

• Separate interface for C-bits

• Detect and generate DS3 AIS, and idle signals

• Transmit reference generator for serial operation

• Transmit and receive FEAC channel under software control

• Transmit single errors: framing, FEBE, C-bit parity, and P-bit parity

• FEBE, C-bit and P-bit performance counters

• Transmit-to-Receive and Receive-to-Transmit loopbacks

Applications

• Subrate multiplexing

• Wideband data or video transport

• DS3 monitor and test

• Channel extenders
