The VSC8221 is the smallest, lowest power Gigabit Ethernet (GE) 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.
Very low power consumption: less than 700 mW
Single 3.3 V power supply with on-chip regulator
Supports PICMG 2.16 and 3.0 Ethernet backplanes at approximately 500 mW
High-performance 1.25 Gbps SerDes supports SGMII and SerDes-to-Cat5 interfaces
Full suite of BIST, MAC, far-end loopback, and connector loopback modes
Over 150 m of Cat5 reach with the industry's highest noise tolerance
