Gigabit Ethernet switches seem so last year. Yet Vitesse Semiconductor's SparX-G16 and SparX-G24 system-on-a-chip (SoC) solutions reduce the number of required passive components in switch designs while adding security, quality of service (QoS), and cost savings. Targets include small office/home-office (SOHO), small-medium business (SMB), and small-medium enterprise (SME) desktop switches as well as consumer wireless and DSL broadband routers.
The SparX-G16 (VSC7389) and SparX-G24 (VSC7390) are 16- and 24-port Gigabit Ethernet layer 2 switches (see the figure). Their eight integral 10/100/ 1000-Mbit/s copper physical-layer (PHY) transceivers cut size, cost, and power consumption thanks to their integral CPU and line-termination components. The VSC7389 has eight SGMII ports, while the VSC7390 has 16 SGMII ports.
