XTF-821, 10/100/1000M/2.5G Ethernet Transceiver

The XTF-821 is a 10BASE-Te, 100BASE-TX, 1000BASE-T and 2.5GBASE-T transceiver highly integrated into a single monolithic CMOS chip, and is compatible with both the IEEE 802.3 standard and the NBASE-T Alliance PHY. It performs all the necessary physical layer functions for 10BASE-Te, 100BASE-TX, 1000BASE-T and 2.5GBASE-T ethernet over CAT.5e UTP cable.
