The KSZ8873MLL/FLL/RLL is Micrel’s third generation fully integrated 3-port switch. The two PHY units of KSZ8873MLL/RLL support 10BASE-T and 100BASE-TX. The KSZ8873FLL supports 100BASE-FX. The devices have been designed for cost sensitive systems, however, still offer a multitude of features, such as switch management, port and tag based VLAN, QoS priority, one MII interfaces and CPU control and data interfaces. The KSZ8873MLL/FLL/RLL is an excellent choice for VoIP Phone, Set-top/Game Box, SOHO Residential Gateway, industrial Ethernet systems and as a standalone 3-port switch. The KSZ8873MLL/FLL/RLL Evaluation Board provides a convenient means to evaluate the KSZ8873MLL/FLL/RLL’s rich feature set. Easy access is provided to all of the KSZ8873MLL/FLL/RLL pins, with jumpers and interface connectors allowing quick configuration and re-configuration of the board. MIIM, EEPROM programming, SPI emulation software are also provided to access the more extensive features of the KSZ8873MLL/FLL/RLL, via a PC USB port.
