APPLICATIONS

IDT77211

Keyꢀeatures

Descriptions

^◆Full-duplex Segmentation and Reassembly (SAR) at

155 Mbps "wire-speed" (310 Mbps aggregate speed).

^◆Performs ATM layer protocol functions.

TheIDT77211NICStAR^™isamemberofIDT'sfamilyofproductsfor

AsynchronousTransferMode(ATM)networks. TheNICStARperforms

both the ATM Adaption Layer (AAL) Segmentation and Reassembly

(SAR)functionandtheATMlayerprotocolfunctions.

^◆Supports AAL5, AAL3/4, "AAL0" and "Raw Cell" formats.

^◆Supports Constant Bit Rate (CBR)Variable Bit Rate (VBR)

and Unassigned Bit Rate (UBR) service classes.

^◆Reassembles received CS-PDUs directly into host memory.

^◆Two buffer pools for independant or chained reassembly

^◆Segments CS-PDUs ready for transmission directly from

host memory.

theNICStARuseshostmemory,ratherthanlocalmemory,toreassemble

ConvergenceSublayerProtocolDataUnits (CS-PDUs) fromATMcell

payloads receivedfromthe network. Whentransmitting, as CS-PDUs

becomeready,theyarequeuedinhostmemoryandsegmentedbythe

NICStARintoATMcellpayloads. Fromthis,theNICStARthencreates

complete 53-byte ATM cells which are sent through the network. The

NICStAR'son-chipPCIbusmasterinterfaceprovidesefficient,lowlatency

DMAtransferswiththehostsystem,whileit'sUTOPIAinterfaceprovides

directconnectiontoPHYcomponentsusedin25.6Mbpsto155MbpsATM

networks.

^◆PCI bus master interface for efficient, low latency DMA

transfers with host system.

^◆Operates with ATM networks up to 155.52 Mbps.

^◆Up to 16K open transmit connections.

^◆Up to 16K simultaneous receive connections.

^◆Glue-less integration to host system's PCI bus.

^◆UTOPIA Interface to PHY.

TheIDT77211isfabricatedusingstate-of-the-artCMOStechnology,

providingthehighestlevelsofintegration,performanceandreliability,with

thelow-powerconsumptioncharacteristicsofCMOS.

^◆Utility & Management Interface to PHY.

^◆Standalone controller: embedded processor not required.

^◆Supports high-performance, lowest-cost ATM NIC solution.

^◆Supports Big/Little endian on PCI interface
