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.
