LOCAL ATM SAR & PHYSICAL LAYER

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

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.
