8-Port 10 Mbit/s Switch
Preliminary PM3350 ELAN 8x10
TYPICAL APPLICATIONS
LOW-COST 10 Mbit/s SWITCHES
The ELAN 8×10 chip can act as a stand-alone managed or unmanaged switching device in low-cost, compact switch applications.
Eight to sixty-four ports of 10BaseT switches can be built using the internal PCI expansion port. A typical system would use the
following:
• PM3350 (one for every eight ports),
• two 256k × 16-bit 60 ns EDO or Fast Page Mode DRAM chips per ELAN 8×10 chip,
• an EPROM or EEPROM (initialization, configuration, SNMP support firmware),
• quad Ethernet interface adapters (LXT944), and
• appropriate passive components.
A block diagram of a typical 8-port 10BaseT stackable switch is shown.

LOW-COST 10/100 Mbit/s SWITCHES
The ELAN 8×10 chip can be part of a fully managed 10/100 switch using the PM3351 ELAN 1×100 10/100 Mbit/s switch chip.
Together they can form a workgroup or desktop application. A block diagram of a typical 32-port 10BaseT stackable switch with
two 10/100 Mbit/s ports is shown. The PCI expansion bus is used to seamlessly connect the ELAN 8×10s and ELAN 1×100s.
