RTL8111F-CG原装 以太网芯片 的描述:
The Realtek RTL8111F-CG Gigabit 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 RTL8111F 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 RTL8111F supports the PCI Express 1.1 bus interface for host communications with power management, and is compliant with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet.
It also supports an auxiliary power auto-detect function, and will auto-configure related bits of the PCI power management registers in PCI configuration space. The RTL8111F features embedded One-Time-Programmable (OTP) memory to replace the external EEPROM (93C46/93C56/93C66).
Advanced Configuration Power management Interface (ACPI)—power management for modern operating systems that are capable of Operating System-directed Power Management (OSPM)—is supported to achieve the most efficient power management possible.
PCI MSI (Message Signaled Interrupt) and MSI-X are also supported. In addition to the ACPI feature, remote wake-up (including AMD Magic Packet and Microsoft Wake-up frame) is supported in both ACPI and APM (Advanced Power Management) environments. To support WOL from a deep power down state (e.g., D3cold, i.e., main power is off and only auxiliary exists), the auxiliary power source must be able to provide the needed power for the RTL8111F.
The RTL8111F supports Protocol offload. It offloads some of the most common protocols to NIC hardware in order to prevent spurious wake up and further reduce power consumption.
The RTL8111F can offload ARP (IPv4) and NS (IPv6) protocols while in the D3 power saving state.
