Ethernet Switch Chips Deliver Eight Or Nine Ports For Voice, Video, Data

Offering eight and nine 10/100-Mbit Ethernet ports respectively, the KS8997 and KS8999 target voice, video, and data applications in cost-sensitive small-office/home-office systems. The chips support DiffServ and IEEE 802.1p to prioritize different classes of voice, video, and data traffic, delivering better quality-of-service than previous switch chips. Designed for low-power operation, they can be housed in low-cost 128-lead PQFPs. Included on both are the MACs, the PHYs, a switch engine, the buffer memory, and a media-independent interface, reducing system complexity and cost. The chips also support auto MDI/MDIX, eliminating the need for crossover cables. In lots of 1000, the KS8997 and KS8999 cost $15.32 and $19.32, respectively. Samples are available from stock.
