PCIe Networking Adapter 2.5 Gbps Cudy PE25

The Realtek RTL8125-CG 10/100/1000M/2.5G Ethernet controller
combines a four-speed IEEE 802.3 compatible Media Access
Controller(MAC) with a four-speed Ethernet transceiver, PCI
Express bus controller, and embedded memory. With state-of-the-art
DSP technology and mixed-mode signal technology, the RTL8125
offers high-speed transmission over CAT 5e UTP cable or CAT 3
UTP(I0Mbps only) cable. Functions such as Cross-over Detection
and Auto-Correction, polarity correction, adaptive equalization, crosstalk
cancellation, echo cancellation, timing recovery and error correction
are implemented to provide robust transmission and
reception capability at high speeds.
