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

identical rich features of the KS8993F.

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.

Features

•

First single-chip 10BASE-T/100BASE-TX to

100BASE-FX media converter with TS-1000 OAM

Integrated 3-Port 10/100 Ethernet Switch with

3 MACs and 2 PHYs

Unique User Defined Register (UDR) feature brings

OAM to low cost/complexity nodes

The KS8993F provides remote loop back and OAM

(Operation, Administration and Maintenance) to manage

subscriber access network from carrier center side to

terminal side.

Automatic MDI/MDI-X crossover with disable and

enable option

Non-blocking switch fabric assures fast packet

delivery by utilizing an 1K MAC Address lookup table

and a store-and-forward architecture

Comprehensive LED indicator support for link, activity,

full/half duplex and 10/100 speed

Full complement of MII/SNI, SPI, MIIM, SMI and I2C

interfaces

Low Power Dissipation:< 800mW (includes PHY

transmit drivers)

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.
