Features and Specifications
The Realtek Rtl8211 8212 11 is a highly integrated Ethernet transceiver that supports 10Base-T, 100Base-TX, and 1000Base-T IEEE 802.3 standards. It provides all the necessary physical layer functions to transmit and receive Ethernet packets over CAT.5 UTP cable. Some of the features and specifications of the Realtek Rtl8211 8212 11 are as follows:
It supports Reduced Gigabit Media Independent Interface (RGMII) for data transfer between MAC and PHY. It also supports various RGMII signaling voltages, including 3.3, 2.5, 1.8, and 1.5V.
It supports IEEE 802.3az-2010 (Energy Efficient Ethernet), which reduces power consumption during periods of low link utilization.
It supports Wake-on-LAN (WOL), which allows the system to be remotely powered on by a network message.
It supports Interrupt function, which notifies the system of network events, such as link status change or packet reception.
It supports Parallel Detection, Crossover Detection & Auto-Correction, Automatic polarity correction, Baseline Wander Correction, and other functions to provide robust transmission and reception capabilities at different speeds.
It supports up to 120m for CAT.5 cable in 1000Base-T mode.
It supports Green Ethernet (1000/100Mbps mode only), which reduces power consumption by adjusting the signal strength according to the cable length.
It incorporates a state-of-the-art switching regulator that requires a well-designed PCB layout in order to achieve good power efficiency and lower the output voltage ripple and input overshoot.
It comes in a 40-pin QFN Green package with a 55 nm process and ultra-low power consumption. The RTL8211FI-CG variant is manufactured to industrial grade standards.
