PHY 1-CH 1.25Gbps 100-Pin TF-BGA

Single Port 10/100/1000BASE-T PHY with 1.25 Gbps SerDes for SFPs / GBICs. 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 industry leading tolerance to NEXT, FEXT, Echo, and system noise.
