Functional Description
The KSZ8893FQL is a single-chip Fast Ethernet media converter. It contains two 10/100 physical layer transceivers
and three Media Access Control (MAC) units with an integrated Layer 2 managed switch.
On the media side, the KSZ8893FQL supports IEEE 802.3 10Base-T and 100Base-TX on both PHY ports. In Media
Converter (MC) applications, PHY port 1 is the fiber port and supports 100Base-FX, 100Base-SX and 10Base-FL.
The KSZ8893FQL has the flexibility to reside in either a managed or unmanaged design. In a managed design, the
host processor has complete control of the KSZ8893FQL via the SMI interface, MIIM interface, SPI bus, or I
2C bus. An
unmanaged design is achieved through I/O strapping and/or EEPROM programming at system reset time.
Physical signal transmission and reception are enhanced through the use of patented analog circuitries that make the
design more efficient and allow for lower power consumption and smaller chip die size.
Functional Overview: Media Conversion
TS-1000 OAM Operation
The KSZ8893FQL implements Japan’s TTC (TELECOMMUNICATION TECHNOLOGY COMMITTEE) TS-1000 version
2, OAM sub-layer, which resides between RS and PCS layer in the IEEE 802.3 Standard. The OAM sub-layer is
provided in 100Base-FX mode, and is used by the KSZ8893FQL to send and receive OAM frames. These special
frames are used for the transmission of OAM (Operations, Administration, Management) information between center
MC and terminal MC. Key TS-1000 OAM 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
OAM Frame Format
The TS-1000 OAM (Operations, Administration, and Management) Frame Format is shown on the following page.
