VSC8211
Single Port 10/100/1000BASE-T PHY and 1000BASE-X PHY with SGMII, SerDes, GMII,
MII, TBI, RGMII / RTBI MAC Interfaces
GENERAL DESCRIPTION:
The VSC8211 is ideal for Media Converter and 100BASE-FX applications. Its low power consumption and patented
line driver technology reduce the cost and complexity of Gigabit Ethernet system designs. The VSC8211’s integrated
1.25 Gbps SerDes and Auto-Media Sense™ feature allow system designers to support Category-5 twisted pair, fiber
optic, and backplane interfaces from a single device. Vitesse’s mixed signal and DSP architecture yields robust
performance, supporting both full and half duplex 10BASE-T, 100BASE-TX, and 1000BASE-T over >140m of Category
5, unshielded twisted pair (UTP) cable, with industry leading tolerance to NEXT, FEXT, Echo, and system noise.
