KSZ8993F شرح
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 100BASE-
TX 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.
