Enhanced Three-Speed Ethernet Controllers
15.6.1.6
This section describes the reduced ten-bit interface (RTBI) intended to be used between the PHYs and the
eTSEC to implement a reduced-pin count version of a SerDes interface for optical-fiber devices in
1000BASE-SX/LX applications.
signals required to establish eTSEC module connection with a PHY. Note that in RTBI the eTSEC
immediately begins auto-negotiation with the SerDes.
A RTBI interface has 15 signals (GE_GTX_CLK125 included), as defined by the RGMII specification
Version 1.2a 9/22/00, and is intended to be an alternative to the IEEE 802.3u MII, the IEEE 802.3z GMII
and the TBI standard for connecting to an Ethernet PHY.

The management signals (MDC and MDIO) are common to all of the Ethernet controllers’ connections
in the system, assuming that each PHY has a different management address.
