RTL8304MB-CG/RTL8304MBI-CG中文资料SINGLE-CHIP 4-PORT 10/100M ETHERNET SWITCH CONTROLLER数据手册Realtek规格书

描述 Description

The RTL8304MB-CG is a 4-port 10/100M Ethernet switch controller that integrates memory, four
MACs, and three physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip.
It supports an RMII interface for external devices to connect to the 4th MAC. The external device could
be a routing engine, HomePNA, HomePlug, or VDSL transceiver depending on the application.
