The VSC8658 is a low-power octal Gigabit Ethernet (GE) transceiver with dual, fully integrated 1.25 G SerDes interfaces. It is designed for use in applications such as multiport switches and routers, where its compact ball grid array (BGA) packaging, low electromagnetic interference (EMI) line driver, and integrated line side termination resistors conserve both power and PC board space. Using the VSC8658 in your design makes it possible to lower the component count of your PB board, sub-assembly, or device without sacrificing chip-centric capabilities or utility. This feature can make it less expensive to produce and more cost-effective to deploy.
