SINGLE PORT FAST ETHERNET SWITCH

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

FEATURES

•

Single-chip, 1-port, full duplex or half duplex, 10/100BaseT switching 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., frame forwarding and

filtering decisions).

•

Performs frame switching at a rate of 200 Mbit/s (full duplex), 100 Mbit/s (half

duplex).

•

Fully compatible with the PM3350, 8-port 10 Mbit/s switch device; may be used

to create a compact and inexpensive mixed 10/100 Mbit/s switching hub.

•

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

•

Filtering and switching at wire rates (up to 148,800 packets per second),

supporting a mix of Ethernet and IEEE 802.3 protocols.

•

Expansion port supports a peak system bandwidth of 1 Gbit/s, and is compatible

with industry-standard PCI bus (version 2.1).

•

Performs all address learning, address table management and aging functions

for up to 32,768 MAC addresses (limited by external memory). Address

learning rate of up to 100,000 addresses per second.

•

Maximum broadcast/multicast at wire rates 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 frame lifetime control.
