RTL8111G datasheet


The Realtek RTL8111GCG/RTL8111GSCG 10/100/1000M Ethernet controller combines a triplespeed IEEE 802.3 compliant Media Access Controller (MAC) with a triplespeed Ethernet transceiver, PCI Express bus controller, and embedded memory. With stateoftheart DSP technology and mixedmode signal technology, the RTL8111G/RTL8111GS offers highspeed transmission over CAT 5 UTP cable or CAT 3 UTP (10Mbps only) cable. Functions such as Crossover Detection and AutoCorrection, polarity correction, adaptive equalization, crosstalk cancellation, echo cancellation, timing recovery, and error correction are implemented to provide robust transmission and reception capability at high speeds.

RTL8211E-VB-CG datasheet


Description :

The Realtek RTL8211E-VB-CG/RTL8211E-VL-CG/RTL8211EG-VB-CG are highly integrated Ethernet transceivers that comply with 10Base-T, 100Base-TX, and 1000Base-T IEEE 802.3 standards. They provide all the necessary physical layer functions to transmit and receive Ethernet packets over CAT.5 UTP cable.

The RTL8211E-VB(VL)/RTL8211EG-VB uses state-of-the-art DSP technology and an Analog Front End (AFE) to enable high-speed data transmission and reception over UTP cable. Functions such as Crossover Detection & Auto-Correction, polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are implemented in the RTL8211E-VB(VL)/RTL8211EG-VB to provide robust transmission and reception capabilities at 10Mbps, 100Mbps, or 1000Mbps.

Data transfer between MAC and PHY is via the Reduced Gigabit Media Independent Interface (RGMII) or Gigabit Media Independent Interface (GMII) for 1000Base-T, 10Base-T, and 100Base-TX. The RTL8211E-VB and RTL8211EG-VB support 3.3V or 2.5V signaling for RGMII/GMII. The RTL8211E-VL supports 1.5/1.8V signaling for RGMII.


1. Built-in Wake-on-LAN (WOL)
2. Supports Interrupt function
3. Supports Parallel Detection
4. Crossover Detection & Auto-Correction
5. Automatic polarity correction
6. Supports PHYRSTB core power Turn-Off
7. Baseline Wander Correction
