Micrel, Inc.
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
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:
