Gigabit Ethernet Transceiver
Hardware Interfaces
Reduced Ten-Bit Interface (RTBI)
The RTBI is fully compliant with RGMII rev 1.3 specifica-
tion. The RTBI mode is selected by setting the hardware
configuration pins MAC_IF_SEL[2:0] = 101 or 111. (See
Table 10 on page 30 for further information on
MAC_IF_SEL pin operation.)

dependent (transformer) interface. The MAC trans-
mits bit 5 on a positive transition of TXC and bit 10 on
the negative transition of TXC.
The ET1011C generates a 125 MHz clock to synchro-
nize receive data.
The ET1011C transmits data that is synchronized with
RXC to the MAC. The ET1011C transmits bits 3:0 on
a positive transition of RXC and bits 8:5 on the nega-
tive transition of RXC.
The ET1011C transmits bit 5 and bit 10 synchronized
with RXC to the MAC. The ET1011C transmits bit 5
on a positive transition of RXC and bit 10 on the nega-
tive transition of RXC.
