M28525/9 Data Sheet
Inverse Multiplexing for ATM (IMA) Family
The M2852x family of devices provides system designers with a complete integrated IMA solution for up to 32 ports.
All devices include a Transmission Convergence block to perform cell delineation, 512 K internal RAM to meet ATM
forum requirements for differential delay compensation and a dual mode (UTOPIA or Serial) PHY layer interface.
Source code for all required software functions is available from Mindspeed. The M28529 supports 32 IMA groups
with 1-32 links per group.
The TC block is capable of bit level cell delineation, which allows for direct connection DSL serial data streams
without a frame sync pulse. Individual ports can be operated in a 'pass thru' mode without the IMA overhead.
The M28529 provides direct connection to 32 serial/interleaved highway links or a PHY side UTOPIA bus. In
addition, an external memory bus allows the differential delay memory to access up to 2 Mbytes of external
RAM.The M28529 supports both version 1.0 and 1.1 of IMA standard AF-PHY-0086.001
Distinguishing Features
• Complete IMA solution in a single package
• 16 port, M28525
• 32 port, M28529
• Field tested software available
• Up to 32 IMA groups with 1-32 links/group
• Supports 50 ms (beyond the IMA standard requirements for 25 ms)
differential delay with 512K Internal memory
• Memory expandable to 2 M bytes via external bus
• UTOPIA level 2 interfaces
• Glueless serial and interleaved highway interfaces to Mindspeed
Framers
• Octet or Bit level cell delineation
• Variable link data rates (64K–8.192 Mb/s)
