Discriptions
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/dow
