Functional Description
2.1
Overview
The KS8993F is a single-chip Fast Ethernet media converter. It contains two 10/100 physical layer transceivers, three
MAC (Media Access Control) units, layer-2 managed switch, and frame buffer. On the media side, the KS8993F
supports IEEE 802.3 10BASE-T, 100BASE-TX on ports 1 and 2, and 100BASE-FX on port 1.
The KS8993F implements the unique OAM sub-layer, which resides between RS and PCS layer in the IEEE 802.3
standard. The KS8993F sends and receives an OAM frame that has a fixed length of 96 bits. This special frame is
used for the transmission of OAM information between center MC and terminal MC.
The KS8993F has the flexibility to reside in an unmanaged or managed design. An unmanaged design is achieved
through I/O strapping or EEPROM programming at system reset time. In a managed design, a host processor has
complete control of the KS8993F via the SMI, MIIM, SPI or I
2C interface.
The KS8993F supports advanced Quality Of Service, port mirroring, rate limiting, broadcast storm protection, and
management via SNMP.
The KS8993FL is the single supply version with all the identical rich features of the KS8993F. In the KS8993FL
version, pin number 22 provides 1.8V output power to the KS8993FL’s VDDC, VDDA and VDDAP power pins. Refer
to the pin description of pin number 22 in section 1.2, Pin Description and I/0 Assignment, for more details.
Physical signal transmission and reception are enhanced through the use of patented analog circuitry that makes the
design more efficient, and allows for lowest power consumption and smaller chip die size.
2.2
Media Converter Function
The KS8993F is the industry’s first single-chip Fast Ethernet media converter that conforms to the TS-1000 spec. The
TS-1000 spec. has been standardized by the TELECOMMUNICATION TECHNOLOGY COMMITTEE (TTC) of Japan in
May 2002 and can be purchased from TTC. Some key TS-1000 features include:
Private point-to-point communication between two TS-1000 compliant devices
96 bits (12 bytes) frames for the transmission of OAM information between center MC and terminal MC
Transmission of MC status between center MC and terminal MC
Automatic generation of OAM frame to inform MC link partner of local MC’s status change
Transmission of vendor code and model number information between center MC and terminal MC for device
identification
Inquisition of terminal MC status by center MC
Remote loop back for diagnostic by center MC
