PM3350 ELAN 8 X10

8 PORT ETHERNET SWITCH

DESCRIPTION

The PM3350 is a low-cost, highly integrated, stand-alone, single-chip switching device

for Ethernet/IEEE 802.3 switching and bridging applications. The device supports all

processing required for switching Ethernet/IEEE 802.3 packets between eight

independent half-duplex 10 Mbit/s ports. In addition, a switch built around the ELAN

8x10 can be expanded simply by connecting up to 7 additional devices to the on-chip

1 Gbit/s expansion port. Switch configuration and management can be performed either

remotely (in-band), via the on-chip SNMP MIB, agent and integrated TCP/UDP/IP

stack, or from a local CPU interfaced to the expansion port. The ELAN 8x10 also

collects per-port and per-host RMON statistics at wire rates on all ports. The ELAN

8x10 chip contains all the required elements of a high-performance Ethernet switch:

MAC-layer interfaces, buffer FIFOs, a high-speed DMA engine for fast packet transfers,

a local memory interface for up to 16 MB of external buffer memory, a compatible PCI

bus master and slave unit for modular expansion, and a switch processing unit that

implements the switching and bridging functions. The only additional components

required to create a complete 8-port switch are Ethernet Medium Access Unit (MAU)

devices, line transformers, a bank of external memory and a system clock.

The ELAN 8x10 device is implemented in high-density CMOS technology for low cost

and high performance. It is available in a 256-pin SBGA, and is ideally suited for

compact, low-cost desktop, workgroup and departmental Ethernet switching

applications.
