Description

The MT90732 E2/E3 Framer (E2/E3F) is a CMOS

VLSI device that provides the functions needed to

frame a wideband payload to one of four CCITT

Recommendations. G.742, G.745, G.751, or G.753.

The E2/E3 Framer interfaces to line circuitry with

either dual rail or NRZ signals. On the terminal side,

the interface can be either nibble-parallel or bit-

serial.

•

Line side interface

- Dual rail or NRZ

HDB3 codec for dual rail I/O

Terminal side interface

•

- Nibble-parallel

- Bit-serial

•

Transmit reference generator for bit-serial I/O

Microprocessor or control leads

I/O port for service bits

The MT90732 can be operated with or without a

microprocessor.

When

interfaced

with

microprocessor, the E2/E3 Framer provides an 8-

byte memory map for control, performance counters

and alarm status. The MT90732 provides a transmit

and receive interface port for accessing the
