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.
The MT90732 can be operated with or without a
microprocessor.
When
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
overhead
bits
from
recommendations. The overhead bits can also be
accessed by the microprocessor via the memory
map.
