The VSC8221 is the smallest, lowest power Gigabit Ethernet over copper PHY available and is ideal for
SFP/GBIC and Media Converter applications. It is the only triple speed copper SFP PHY to meet the stringent
MSA power consumption requirement of <1W for the entire module. Its integrated switching regulator
enables it to be powered by a single 3.3V power supply, reducing board space requirements and system cost.
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
