Features  
Ordering Information  
Cost effective, single chip, 4-port ATM IMA and  
UNI processor  
MT90221AL  
208 Pin MQFP  
Up to 4 IMA groups over 4 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  
(MT90221 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
