December 1999

Features

Ordering Information

•

Cost effective, single chip, 8-port ATM IMA and

UNI processor

MT90220AL

208 Pin MQFP

Up to 4 IMA groups over 8 T1/E1 links can be

implemented

-40°C to +85°C

Supports MIXED mode; links not assigned to an

IMA group can be used in UNI mode

•

Provides Header Error Control (HEC)

veriﬁcation and generation, error detection,

Filler cell ﬁltering (IMA mode) and Idle/

Unassigned cell ﬁltering (UNI mode)

Versatile PCM Interface to most popular T1 or

E1 framers, reducing development time

Supports Symmetrical and Asymmetrical

Operation

•

Provides statistics to support MIB

Connects to popular asychronous SRAM

Provides statistics on the number of HEC errors

Supports both Common Transmit Clock (CTC)

and Independent Transmit Clock (ITC) clocking

modes

8 bit Microprocessor Interface, compatible with

Intel and Motorola

•

Supports T1 ISDN lines

•

3.3V operation / 5V tolerant inputs

MQFP-208 pin

Provides UTOPIA Level 2 MPHY Interface

(MT90220 device slaved to ATM device)

JTAG Test support

•

Complies with ITU G.804 recommendations for

performing cell mapping into T1 and E1

transmission systems

Provides ATM framing using cell delineation

according to the ITU I.432 cell delineation

process
