Preliminary PM3351 ELAN 1x100
Single-Port 10/100 Mbit/s Ethernet Switch
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.
