DescriptionMindspeed M28525 Series Inverse Multiplexing for ATM (IMA) Family | 27mm PBGA, 484 pins, -40 °C to 85 °C Operating Temperature.
OverviewThe 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 FeaturesComplete 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)
