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

AM79C972BKC Datasheet PDF -PCI Ethernet Controller – AMD

Part Number : AM79C972BKC

Function : PCnet-FAST enhanced 10/100 Mbps PCI Ethernet Controller

Package : Plastic Quad Flat Pack (PQR160) Type

Manufacturers : Advanced Micro Devices

Pinouts :

AM79C972BKC datasheet


Description :

The Am79C972 PCnet-FAST+ controller is a highly integrated 32-bit full-duplex, 10/100-Megabit per second (Mbps) Ethernet controller solution, designed to address high-performance system application requirements. It is a flexible bus mastering device that can be used in any application, including network-ready PCs and bridge/router designs. The bus master architecture provides high data throughput and low CPU and system bus utilization. The Am79C972 controller is fabricated with advanced low-power 3.3-V CMOS process to provide low operating current for power sensitive applications.

The Am79C972BKC PCnet-FAST+ controller also has several enhancements over its  predecessor, the Am79C971 PCnet-FASTdevice. In addition to integrating the SRAM on chip, it further reduces system implementation cost by the addition of a new EEPROM programmable pin (PHY_RST), an internal oscillator circuit eliminating the need for an external crystal, and the integration of the PAL function needed for Magic Packet application. The PHY_RST pin is implemented to reset the external PHY without increasing the load to the PCI bus and to block RSTto the PHY when PG input is LOW.
