• Manufacturer Part Number: mt90224
• Description: 8-port Ima/tc Phy Device
• Manufacturer: Zarlink Semiconductor

1.0
The MT90222/3/4, supported by software, implements the ATM Forum Inverse Multiplexing for Asynchronous
Transfer Mode (IMA) Specification. Actions are implemented by the MT90222/3/4 and decisions are made by the
software. This approach minimizes the impact of any changes that might occur in the specification.
The MT90222/3/4 supports the following two major modes of operation:
•
•
Up to eight IMA Groups can be implemented (4 groups - 0,1,2,3 for MT90222) Any of the available serial (TDM)
interfaces can be assigned dynamically to any of these IMA Groups. A different UTOPIA PHY address is assigned
to each of the IMA Groups.
The TC mode is used to transfer the cells from the UTOPIA Interface to a serial (TDM) port without any overhead.
Up to 16 UTOPIA PHY addresses can be supported in TC mode (one per serial port).
The MT90222/3/4 also supports a mixed mode where the TDM Interfaces not assigned to an IMA Group can be
used in TC mode.
