It offers an extensive feature set that includes rate limiting, tag/port-based VLAN, QoS priority, management, management information base (MIB) counters, MII/SNI, and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications. The KS8893M contains two 10/100 transceivers with patented mixed-signal low-power technology, three media access control (MAC) units, a high-speed non-blocking switch fabric, a dedicated address lookup engine, and an on-chip frame buffer memory. Both PHY units support 10BASE-T and 100BASE- TX. In addition, one PHY unit supports 100BASE- FX. The KS8893ML is the single power supply version with all the identical rich features of the KS8893M. ___________________________________________________________________________________________________ Functional Diagram 1K LOOK-UP ENGINE QUEUE MANAGEMENT BUFFER MANAGEMENT FRAME BUFFERS MIB COUNTERS EEPROM INTERFACE 10/100 MAC 1 10/100 MAC 2 10/100 MAC 3 10/100 T/TX/FX PHY 1 10/100 T/TX PHY 2 HP AUTO MDIX HP AUTO MDIX SNI RMII/MII/ SNI SPI SPI CONTROL REGISTERS MIIM SMI STRAP IN CONFIGURATION LED DRIVERS I2C P1 LED[3:0] P2 LED[3:0] |
