General Description
The RTL8208 is a highly integrated 8 port, 10Base-T/100Base-TX/FX, Ethernet transceiver implemented in 0.25µm CMOS technology. It is currently the world’s smallest Octal-PHY chip package with many special patented features. Traditional SD pins in 100Base-FX are omitted by Realtek patent to obtain fewer pin-count. Flexible hardware settings are provided to configure the various operating modes of the chip. The RTL8208 consists of 8 separate and independent channels. Each channel consists of an RMII/SMII/SS-SMII interface to MAC controller, and hardware pins are used to configure the interface for RMII, or SMII, or SS-SMII mode. In RMII mode, another hardware pin is used to set port-pair loop mode (PP-LPBK mode), which can extend physical transmission length or perform physical media transport operations without any switch controller.
Features
Supports 8-port integrated physical layer and transceiver for 10Base-T and 100Base-TX
Up to 8 ports support of 100Base-FX
Reduced 100Base-FX interface (patented)
