描述 Description

General Description
The KSZ8895MQ/RQ/FMQ is a highly-integrated Layer 2 managed five-port switch with optimized design and plentiful features. It is designed for cost-sensitive 10/100Mbps five-port switch systems with lowest power consumption, on-chip termination and internal core power controller. These features will save more system cost. It supports high-performance memory bandwidth, shared memory based switch fabric with non-blocking configuration. It also provides an extensive feature set such as power management, programmable rate limit and priority ratio, tag/port-based VLAN, packets filtering, four queues QoS prioritization, management interfaces and MIB counters. 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 configurations provided by the KSZ8895 family enables the flexibility to meet different requirements:
• KSZ8895MQ: Five 10/100Base-T/TX transceivers, one SW5-MII and one P5-MII interface
• KSZ8895RQ: Five 10/100Base-T/TX transceivers, one SW5-RMII and one P5-RMII interface
• KSZ8895FMQ: Three 10/100Base-T/TX transceiver on Ports 1, 2, 5 and two 100Base-FX transceivers on Ports 3, 4, one SW5-MII and one P5-MII interfaceAll 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.
