Features
Cost effective, single chip, 8-port ATM IMA and
UNI processor
Up to 4 IMA groups over 8 T1/E1 links can be
implemented
Supports MIXED mode; links not assigned to an
IMA group can be used in UNI mode
Versatile PCM Interface to most popular T1 or
E1 framers, reducing development time
Supports Symmetrical and Asymmetrical
Operation
Supports both Common Transmit Clock (CTC)
and Independent Transmit Clock (ITC) clocking
modes
Supports T1 ISDN lines
Provides UTOPIA Level 2 MPHY Interface
(MT90220 device slaved to ATM device)
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
Provides Header Error Control (HEC)
verification and generation, error detection,
Filler cell filtering (IMA mode) and Idle/
Unassigned cell filtering (UNI mode)
Provides statistics to support MIB
Connects to popular asychronous SRAM
Provides statistics on the number of HEC errors
8 bit Microprocessor Interface, compatible with
Intel and Motorola
3.3V operation / 5V tolerant inputs
MQFP-208 pin
JTAG Test support
