TYPICAL APPLICATION
LOW-COST 10/100 Mbit/s ETHERNET SWITCH
The ELAN 1
×
100 chip is used to build low-cost 10/100 Mbit/s switches for server/backbone applications. A switch can be created
from the following:
PM3351s (one for every 100 Mbit/s port required),
one to seven PM3350s (one for every eight 10 Mbit/s ports required),
a bank of memory per device (60 ns EDO DRAM for each PM3350,
15 ns SRAM for each PM3351) for holding frame buffers and switching tables,
a single 256k
×
8-bit EPROM or EEPROM (initialization, configuration, and SNMP support firmware),
quad 10BaseT interface adapters (LXT944) for the PM3350s,
one 100 Mbit/s PHY device per PM3351, and
appropriate passive components.
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.
