Product Summary
The RTL8305SC is a five ports ethernet switch controller that integrates memory, five macs, and five physical transceivers for 10base-t and 100base-tx operation into a single chip. All ports supports 100base-fx, which pins with utp ports and needs no sd+/- pins, a development using realtek proprietary technology. To compensate for the lack of auto-negotiation in 100base-fx applications, the RTL8305SC can be forced into 100base-fx half or full duplex node, and can enable or disable flow control in fiber mode.
