IP178G

Product Overview

IP178G is an IC Plus 8-port 10/100Mbps Fast Ethernet integrated switch controller designed for low-power unmanaged switching applications. The device integrates eight 10/100 Ethernet PHYs, a switch fabric, packet buffer, MAC table, QoS, VLAN and power-management functions in a compact 68-pin QFN package. With IEEE 802.3az energy-efficient Ethernet support, Auto MDI/MDIX, port mirroring and link aggregation, IP178G is well suited for desktop switches, embedded Ethernet equipment and industrial networking systems.

Applications

IP178G can be used in networking systems requiring a compact and low-power 8-port Fast Ethernet switching solution. Typical applications include unmanaged desktop switches, embedded Ethernet switches, industrial networking equipment, access-control systems, surveillance-network equipment and communication gateways. Its integrated PHYs, packet buffer, VLAN, QoS and energy-saving functions help reduce external component count while simplifying low-cost Ethernet switch designs.

Quality & Sourcing

Antrex Electronics can support IP178G sourcing with stock availability checks, RFQ quotation, QFN package confirmation, date code review and shipment arrangement. Buyers are encouraged to provide required quantity, target price, acceptable date code and application requirements, especially when distinguishing IP178G from IP178GH or IP178GI versions.

For quality control, Antrex Electronics can help arrange product photos, label review, visual inspection and third-party testing support when required. OEMs, EMS providers, networking equipment manufacturers, repair centers and electronic component buyers are welcome to send BOM lists or hard-to-find part requests for sourcing assistance.
