Vitesse Delivers 16- and 24-port GigE System-on-a-Chip with PHYs

Vitesse Semiconductor began sampling 16- and 24-port Gigabit Ethernet Switches with eight integrated PHYs and an embedded "V-Core" processor. The system-on-a-Chip (SoC) solution reduces the number of required active components in web-managed smart switch systems.

Vitesse said the delivery of its 16-port SparX-G16 and the 24-port SparX-G24 devices marks the next-step in the on-going evolution of fully integrated, Layer 2 Gigabit Ethernet switch IC and SoC solutions.

The chips deliver advanced QoS features such as Differentiated Service Code Point (DSCP) remarking, which permits enterprise network managers and service providers to more accurately manage the priority of traffic based on service agreements with their customers. This functionality also decreases the threat of internal and external security breaches through packet filtering based on Source IP, ARP, and TCP/UDP filters; in addition, the devices offer flexible and configurable rate shaping for both ingress and egress directions to enable enforcement of pre-negotiated bandwidth levels, and up to 8K IP Multicast group entries for applications such as video distribution.
