描述 Description

IP178D integrates an 8-port switch controller, SSRAM, and 8 10/100 Ethernet transceivers. Each of the transceivers complies with the IEEE 802.3, IEEE 802.3u, and IEEE 802.3x specifications. The transceivers are designed in DSP approach in 0.16um technology; they have high noise immunity and robust performance.

IP178D supports a lot of QoS function, including 802.1p, DiffServ, TCP/UDP port number and High priority port. User could enable QoS function from Pin or EEPROM.

IP178D also supports port mirror function for each port. User could monitor RX and TX port.

There are two fiber ports, port 6 and port 7, could be enable and disable from pin.
