Quad Port 10/100/1000BASE-T PHY with R/GMII, R/TBI Interfaces
proprietary DSP technology yields robust performance and low power consumption, supporting
1000BASE-T over unshielded twisted pair (UTP) cable, with more than 5dB of design margin with respect
to all worst-case impairments (NEXT, FEXT, Echo, and system noise sources).
The VSC8204 is a low power, low cost, quad port Gigabit Ethernet PHY. It is ideal for Gigabit Ethernet
Switch applications that require a GMII/MII, RGMII, TBI, or RTBI MAC / Switch interface. Vitesse’s
