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 interna...
