PRODUCT OVERVIEW
The Marvell
at desktop Gigabit Ethernet (GbE) switches in Small-to-Medium Size Business (SMB) networks. The Prestera-DX
GbE packet processors are available in 8-port (98DX81), 16-port (98DX161) and 24-port (98DX241) conTgurations,
integrating Gigabit MACs with embedded buffer memory and integrated SERDES in each port. It is a complete
System-On-Chip (SOC) solution that supports full-wire-speed switching performance with advanced Quality of
Service (QoS) features including IEEE 802.1p, DiffServ and four priority levels per port. Addressing the cost-
sensitive unmanaged desktop switching market, the Prestera-DX81/DX161/DX241 devices enable system
vendors to design affordable, plug-and-play, high-density, small form factor standalone switches.
