General Description

The KSZ8895MQX/RQX/FQX/MLX 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, 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, four-queue 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.

The KSZ8895 family offers three configurations, providing the flexibility to meet different requirements:

? KSZ8895MQX/MLX: Five 10/100Base-T/TX transceivers, One SW5-MII, and One P5-MII interface

? KSZ8895RQX: Five 10/100Base-T/TX transceivers, One SW5-RMII, and One P5-RMII interface

? KSZ8895FQX: Four 10/100Base-T/TX transceivers on Ports 1, 2, 3, and 5 (port 3 can be set to fiber mode). One 100Base-FX transceiver on Port 4. One SW5-MII and One P5-MII interface

All registers of MACs and PHYs units can be managed by the SPI or the SMI interface. MIIM registers can be accessed through the MDC/MDIO interface. EEPROM can set all control registers for the unmanaged mode.

KSZ8895MQX/RQX/FQX are available in the 128-pin PQFP package. KSZ8895MLX is available as a 128-pin LQFP package.
