8 PORT ETHERNET SWITCH

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND PMC-SIERRA, INC. CUSTOMERS ONLY

FEATURES

•

Single-chip, 8-port 10BaseT Ethernet switch device for low-cost unmanaged and

managed networks.

•

On-chip 50 MHz RISC CPU processor core, multi-channel DMA controller,

MAC-layer interface logic, FIFOs, PCI-based expansion port and a flexible

memory controller.

•

CPU supports background applications running on local OS (e.g., SNMP or

RMON), and real-time data oriented applications (e.g., packet forwarding and

filtering decisions).

•

Concurrently switches packets between 8 independent half-duplex ports at the

full Ethernet rate of 10 Mbit/s.

•

Fully compatible with the PM3351 1-port 10/100 Mbit/s switch device; may be

used to create a compact and inexpensive mixed 10/100 Mbit/s switch.

•

Store-and-forward operation with full error checking and filtering.

•

Filtering and switching at wire rates (up to 14,880 packets per second per port),

supporting a mix of Ethernet and IEEE 802.3 protocols.

•

Performs all address learning, address table management and aging functions

for up to 32,768 MAC addresses (limited by external memory) with an address

learning rate of up to 10,000 addresses per second.

•

Maximum broadcast/multicast rate of 14,880 packets per second per port with

configurable broadcast storm rate limiting.

•

Low-latency operation in both unicast and broadcast modes.

•

Implements the Link Partition function to isolate malfunctioning segments or

hosts.

•

IEEE 802.1d compliant spanning-tree transparent bridging supported on-chip,

with configurable aging time and packet lifetime control.

•

On-chip user-enabled backpressure flow control with configurable per-port

buffer thresholds and limits.

•

Expandable to 64 ports without loss in throughput using multiple PM3350

devices via an on-chip 1 Gbit/s expansion port.
