VSC8221
Single Port 10/100/1000BASE-T PHY with 1.25 Gbps SerDes for SFPs / GBICs
GENERAL DESCRIPTION: 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 140m of Category 5, unshielded twisted pair (UTP) cable, with industry leading tolerance to NEXT, FEXT, Echo, and system noise.
