General Description The KSZ8893MQL/MBL, a highly integrated layer 2 managed switch, is designed for low port count, cost-sensitive 10/100 Mbps switch systems. It offers an extensive feature set that includes rate limiting, tag/port-based VLAN, QoS priority, management, management information base (MIB) counters, RMII/MII/SNI, and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications.
Features • Proven Integrated 3-Port 10/100 Ethernet Switch – 3rd generation switch with three MACs and two PHYs fully compliant with IEEE 802.3u standard – Non-blocking switch fabric assures fast packet delivery by utilizing an 1K MAC address lookup table and a store-and-forward architecture – Full duplex IEEE 802.3x flow control (PAUSE) with force mode option – Half-duplex back pressure flow control – HP Auto MDI-X for reliable detection of and correction for straight-through and crossover cables with disable and enable option – Micrel LinkMDTM TDR-based cable diagnostics permit identification of faulty copper cabling – 100BASE-FX support on port 1 – MII interface supports both MAC mode and PHY mode – RMII interface support with external 50MHz system clock – 7-wire serial network interface (SNI) support for legacy MAC – Comprehensive LED Indicator support for link, activity, full/half duplex and 10/100 speed • Comprehensive Configuration Register Access – Serial management interface (SMI) to all internal registers – MII management (MIIM) interface to PHY registers – SPI and I2C Interface to all internal registers – I/0 pins strapping and EEPROM to program selective registers in unmanaged switch mode – Control registers configurable on the fly (port-priority, 802.1p/d/q, AN…) (Continue...) Applications • Typical – Media Converter – FTTx customer premises equipment – VoIP Phone – SOHO Residential Gateway – Broadband Gateway / Firewall / VPN – Integrated DSL/Cable Modem – Wireless LAN access point + gateway – Set-top/Game Box – Standalone 10/100 switch • Upgradeable(1) – Unmanaged switch with future option to migrate to a managed solution – Single PHY alternative with future expansion option for two ports • Industrial – Applications requiring port redundancy and port monitoring – Sensor devices in redundant ring topology
