DESCRIPTION
The PM7375 LASAR-155 Local ATM Segmentation and Reassembly & Physical Layer device is a monolithic integrated circuit that implements SONET/SDH transmission convergence, ATM cell mapping, ATM Adaptation Layer, and PCI Bus memory management functions for a 155.52 or 51.84 Mbit/s ATM User Network Interface.
FEATURES
? Single-chip Peripheral Component Interface (PCI) Bus Local ATM Network Interface using SONET/SDH framing at 155.52 or 51.84 Mbit/s and ATM Adaptation Layer 5 (AAL-5).
? Implements the ATM Physical Layer according to the ATM Forum User Network Interface Specification and ITU-TS Recommendation I.432, and the ATM Adaptation Layer Type 5 (AAL-5) for Broadband ISDN according to ITU-TS Recommendation I.363.
? Provides a direct interface to multimode or single mode optical modules or twisted pair wiring (UTP-5) modules, with on-chip clock recovery and clock synthesis.
? Directly supports a 32-bit PCI bus interface for configuration, monitoring and transfer of packet data, with an on-chip DMA controller with scatter/gather capabilities. Other 32 bit system buses can be accommodated using external glue logic.
? Provides an on-chip 96 cell receive buffer to accommodate up to 270 μs of PCI Bus latency.
? Provides a optional microprocessor port with master and slave capabilities.
? Provides a SCI-PHY and Utopia compliant interface for connection to external PHY layer devices.
? Supports simultaneous segmentation and reassembly of 128 virtual circuits (VCs) in both transmit and receive directions.
? Provides leaky bucket peak cell rate enforcement using 8 programmable peak queues coupled with sub peak control on a per VC basis; provides sustainable cell rate enforcement using the programmable peak cell rate queues and per VC token bucket averaging; and provides aggregate peak cell rate enforcement.
? Provides a generic constant bit-rate (CBR) port.
? Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board test purposes.
? Low power, 0.6 micron, +5 Volt CMOS technology.
? 208 copper slugged plastic quad flat pack (PQFP) package.
APPLICATIONS
? ATM Workstations and Servers
? ATM Bridges, Switches and Hubs
? Multimedia Terminals
