every 100 Mbit/s port required), 1 to 7 PM3350 chips (one for every eight 10 Mbit/s
ports required), a bank of memory per device (60 nsec EDO DRAM for each PM3350,
15 ns SRAM for each PM3351) for holding packet buffers and switching tables, a single
32k x 8-bit EEPROM device for configuration information, two LXT944 10BaseT
interface adapters per PM3350 chip, one LXT970 100 Mbit/s PHY device per PM3351,
and suitable passive components (filters, transformers, crystal oscillators, etc.) A block
diagram of a typical 32-port 10BaseT stackable switching hub with two 100 Mbit/s
server/backbone ports is given in the following diagram. The PCI expansion bus is used
seamlessly to stack the ELAN 8x10s and ELAN 1x100s.
