KSZ8893MQL-AM

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
