2. 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. In addition, the
RTL8208 features very low power consumption, as low as 1.8 W (max.). Additionally, pin-outs are designed to provide
optimized direct routing can be implemented, which simplifies the layout work and reduces EMI noise issues.
