  • Mindspeed (Mindspeed Technologies ) : M28529 / M285295

    32/16 port IMA device

    Mindspeed Technologies' 32-port single-chip IMA processor, M 28529; as well as the 16-port single-chip IMA processor, M28525,  is used for access concentrators, digital subscriber line access multiplexers (DSLAMs), third-generation (3G) wireless networking equipment, multi-service platforms and T1/E1 and DSL line cards.
    Mindspeed’s 32-port M28529 IMA processor is used to provide bandwidth between T1/E1 and T3/E3 speeds and includes 512 Kbytes of on-chip memory that surpasses the standards requirements of 25 milliseconds of differential delay compensation.
    A Transmission Convergence (TC) block provides Utopia 2 or serial line connectivity to T1/E1 framers and DSL transceivers for each link.
