KSZ8895RQXCA

The KSZ8895RQX is a highly-integrated, Layer 2 managed, five-port switch with numerous features designed to reduce system cost. Intended for costsensitive 10/100Mbps five-port switch systems with low power consumption, on-chip termination, and internal core power controllers, it 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, fourqueue QoS prioritization, management interfaces, and MIB counters. The KSZ8895 family provides multiple CPU data interfaces to effectively address both current and emerging fast Ethernet applications when Port 5 is configured to separate MAC5 with SW5-MII/RMII and PHY5 with P5- MII/RMII interfaces.

Advanced Switch Features IEEE 802.1q VLAN support for up to 128 active VLAN groups VLAN ID tag/untag options, per port basis Static MAC table supports up to 32 entries IPv4/IPv6 QoS support Comprehensive Configuration Register Access Serial management interface (MDC/MDIO) to all PHYs registers and SMI interface (MDC/MDIO) to all registers Control registers configurable on the fly QoS/CoS Packet Prioritization Support Per port, 802.1p and DiffServ-based 1/2/4-queue QoS prioritization selection. Integrated 4-Port 10/100 Ethernet Switch Half-duplex back pressure flow control Full-duplex IEEE 802.3x flow control (PAUSE) with force mode option Switch Monitoring Features Loop-back support for MAC, PHY, and remote diagnostic of failure Interrupt for the link change on any ports Low Power Dissipation 0.11µm CMOS technology Commercial temperature range: 0°C to +70°C Industrial Temperature Range: -40°C to +85°C Available in 128-pin PQFP and 128-pin LQFP, lead-free package
