Descriptions

The IDT77211 NICStAR

™

is a member of IDT's family of products for

Asynchronous Transfer Mode (ATM) networks. The NICStAR performs

both the ATM Adaption Layer (AAL) Segmentation and Reassembly

(SAR) function and the ATM layer protocol functions.

A Network Interface Card (NIC) or internetworking product based on

the NICStAR uses host memory, rather than local memory, to reassemble

Convergence Sublayer Protocol Data Units (CS-PDUs) from ATM cell

payloads received from the network. When transmitting, as CS-PDUs

become ready, they are queued in host memory and segmented by the

NICStAR into ATM cell payloads. From this, the NICStAR then creates

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

NICStAR's on-chip PCI bus master interface provides efficient, low latency

DMA transfers with the host system, while it's UTOPIA interface provides

direct connection to PHY components used in 25.6 Mbps to 155 Mbps ATM

networks.

The IDT77211 is fabricated using state-of-the-art CMOS technology,

providing the highest levels of integration, performance and reliability, with

the low-power consumption characteristics of CMOS.
