The Realtek RTL8111EP-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. For the RTL8111EP, the USB redirection feature is implemented by virtual USB over PCIe as defined in the EHCI Specification.
With state-of-the-art DSP technology and mixed-mode signal technology, the RTL8111EP 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.
