General Description
IP178A is an 8 port 10/100 Ethernet integrated switch. It
consists of an 8-port switch controller and eight Fast
Ethernet transceivers. Each of the transceivers complies
with the IEEE802.3, IEEE802.3u, and IEEE802.3x
specifications. The transceivers in IP178A are designed
in DSP approach with advance 0.25um technology; this
results in high noise immunity and robust performance.
Two ports of IP178A can be configured as 100BaseFX.
The IP178A operates in store and forward mode. It
stores the incoming packet to the internal SSRAM and
learns the SA (source address) automatically if the
packet is error free. The SA is stored to the internal
address table. IP178A forwards a packet according to DA
and address table. When the segments of destination
ports are free, it reads the packet from the internal
SSRAM and forwards it to the appropriate ports
according to the address table. The incoming packets
with errors are dropped. IP178A supports IEEE802.3x,
optional backpressure, Auto MDI/MDI-X, CoS, port base
VLAN, one MII port and various LED functions, etc.
These functions can be configured to fit the different
requirements by feeding operation parameters via
EEPROM interface or pull up/down resistors on specified
pins.
