FIFO, Flow Control, VLAN Tagging ,Priority KS8993F/KS8993FL Single Chip Fast Ethernet Media Converter with TS-1000 OAM Revision 1.3 The KS8993FL is the single supply version with all the General Description identical rich features of the KS8993F. The Micrel KS8993F is the industrys first single chip Fast Ethernet Media Converter with built-in OAM functions. The Features KS8993F integrates three MACs, two PHYs, OAM, frame buffer and high performance switch into a single chip. It is First single-chip 10BASE-T/100BASE-TX to ideal for use in 100BASE-FX to 10BASE-T or 100BASE- 100BASE-FX media converter with TS-1000 OAM TX conversion in the FTTx market. Integrated 3-Port 10/100 Ethernet Switch with 3 MACs and 2 PHYs The KS8993F provides remote loop back and OAM Unique User Defined Register (UDR) feature brings (Operation, Administration and Maintenance) to manage OAM to low cost/complexity nodes subscriber access network from carrier center side to Automatic MDI/MDI-X crossover with disable and terminal side. enable option Non-blocking switch fabric assures fast packet The KS8993F supports advanced features such as rate delivery by utilizing an 1K MAC Address lookup table limiting, force flow control and link transparency. and a store-and-forward architecture Comprehensive LED indicator support for link, activity, The KS8993F with built-in Layer 2 switch capability will full/half duplex and 10/100 speed filter packets and forward them to valid destination. It will Full complement of MII/SNI, SPI, MIIM, SMI and I2C discard any unwanted frames and frames with invalid interfaces destination.
