KSZ8895MQ

Product Summary

The KSZ8895MQ is a highly-integrated, Layer 2-managed, five-port switch with numerous features designed to reduce system cost. Intended for cost-sensitive 10/100Mbps five-port switch systems with low power consumption, on-chip termination, and internal core power controllers, the KSZ8895MQ supports high-performance memory bandwidth and shared memory-based switch fabric with non-blocking configuration. Its extensive feature set includes power management, programmable rate limit and priority ratio, tag/port-based VLAN, packets filtering, four-queue QoS prioritization, management interfaces, and MIB counters. Applications are (1)Typical; (2)VoIP Phone; (3)Set-top/Game Box; (4)Automotive; (5)Industrial control; (6)IPTV POF; (7)SOHO residential gateway; (8)Broadband gateway/firewall/VPN; (9)Integrated DSL/cable modem; (10)Wireless LAN access point + gateway; (11)Standalone 10/100 switch.
