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) Robust baseline wander correction for improved 100BASE-TX performance Fully compliant with IEEE 802.3/802.3u IEEE 802.3u compliant Auto-negotiation for 10/100 Mbps control Hardware controlled Flow control advertisement ability Supports RMII/SMII/SS-SMII interfaces Multiple driving capabilities of RMII/SMII/SS-SMII Supports 25MHz crystal as clock source for RMII with 50MHz REFCLK output for MAC RTL8208 Very low power consumption Supports port-pair loop mode (PP-LPBK mode) Supports two Power reduction methods: 1. Power saving mode (cable detection) 2. Power down mode Power-on auto reset function eliminates the need for external reset circuits Flexible LED display modes through 2-wire serial LED control interface 128-pin PQFP 2.5V/3.3V power supply 0.25µm, CMOS technology 2.GENERAL DESCRIPTION
Traditional SD pins in 100Base-FX are omitted by Realtek patent to obtain fewer pin-count.
