Overview
KS8993F/KS8993FL Single Chip Fast Ethernet Media Converter with TS-1000 OAM Revision 1.
3 General Description The Micrel KS8993F is the industry’s first single chip Fast Ethernet Media Converter with built-in OAM functions.
The KS8993F integrates three MACs, two PHYs, OAM, frame buffer and high performance switch into a single chip.
It is ideal for use in 100BASE-FX to 10BASE-T or 100BASETX conversion in the FTTx market.
The KS8993F provides remote loop back and OAM (Operation, Administration and Maintenance) to manage subscriber access network from carrier center side to terminal side.
The KS8993F supports advanced features such as rate limiting, force flow control and link transparency.
The KS8993F with built-in Layer 2 switch capability will filter packets and forward them to valid destination.
It will discard any unwanted frames and frames with invalid destination.
The KS8993FL is the single supply version with all the identical rich features of the KS8993F.
