8111G / RTL8111G  Gigabit Ethernet controller

Integrated 10/100/1000M Ethernet Controller for PCI Express Applications

General Description

The Realtek 8111G-CG/8111GS-CG 10/100/1000M Ethernet controller combines a triple-speed IEEE 802.3 compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, PCI Express bus controller, and embedded memory. With state-of-the-art DSP technology and mixed-mode signal technology, the 8111G/8111GS offers high-speed transmission over CAT 5 UTP cable or CAT 3 UTP (10Mbps only) cable. Functions such as Crossover Detection and Auto-Correction, polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are implemented to provide robust transmission and reception capability at high speeds

The RTL8111G/RTL8111GS supports the PCI Express 1.1 bus interface for host communications with power management, and complies with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet. It supports an auxiliary power auto-detect function, and will auto-configure related bits of the PCI power management registers in PCI configuration space. The RTL8111G/RTL8111GS features embedded One-Time-Programmable (OTP) memory. The RTL8111G/RTL8111GS provides a built-in switching regulator (RTL8111GS) or LDO regulator RTL8111G
