PCI MSI (Message Signaled Interrupt) and MSI-X are also supported. The RTL8111H provides a built-in LDO regulator, and the RTL8111HS provides a built-in switching regulator.Īdvanced 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. The RTL8111H/RTL8111HS features embedded One-Time-Programmable (OTP) memory. 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 RTL8111H/RTL8111HS supports the PCI Express 1.1 bus interface for host communications with power management, and is compatible with the IEEE 802.3u specification for 10/100Mbps Ethernet and the IEEE 802.3ab specification for 1000Mbps Ethernet. 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.
With state-of-the-art DSP technology and mixed-mode signal technology, the RTL8111H/RTL8111HS offers high-speed transmission over CAT 5 UTP cable or CAT 3 UTP (10Mbps only) cable. The Realtek RTL8111H-CG/RTL8111HS-CG 10/100/1000M Ethernet controller combines a triple-speed IEEE 802.3 compatible Media Access Controller (MAC) with a triple-speed Ethernet transceiver, PCI Express bus controller, and embedded memory.
