VSC8221

In Production

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.Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design. MicroCHECK design ...
