    FireStream155G ATM SAR Device

    FireStream 155 G block diagram The FireStream155G is a high performance ATM protocol controller which autonomously terminates ATM Adaptation Layer standard Type 5 (AAL5). ATM cells are passed via a UTOPIA v2.01 compliant interface. Access to system memory is through a 50MHz generic bus interface to achieve simultaneous segmentation and reassembly at an average rate in excess of 155Mbps.
    All ATM Forum traffic classes (ABR, VBR, CBR, UBR) are supported with traffic management to ATM Forum TM4.0 specification on up to 65536 virtual circuits (VCs).
    The device is suited to many ATM applications including ATM switches, access units, adaptor cards, multiprotocol hubs, bridges and routers.
    • Broadband ISDN Adaptation Layer standard Type 5 (AAL5)
    • Simultaneous segmentation and reassembly on up to 64K VCs
    • ABR, VBR, UBR and CBR traffic classes with traffic management compliant to TM4.0
    • Autonomous Resource Management (RM) cell handling
    • 50MHz 32-bit Generic Bus interface compatible with Intel i960 and Motorola 860 buses
    • Write-only interface for PDU handling with copy of SAR registers maintained in host memory
    • Configuration through Generic Bus slave port
    • Transparent ATM cell and cell payload modes (AAL0) with support for Operations and Maintenance (OAM) cells
    • 8/16-bit, up to 52MHz UTOPIA v2.01 level 1 and level 2 compliant cell stream interface with master/slave modes and optional HEC checking on receive
    • Flexible routing tag append / remove mode for direct ATM Switch connection
    • 32-bit Local memory port connects directly to SRAM
    • JTAG compliant to IEEE1149.1
    • Fabricated in CMOS technology with CMOS/TTL compatible 5V tolerant I/O and a 3.3V power supply
    • -40C to +85C Industrial temperature range
