Hardware Interfaces
Ten-Bit Interface (TBI) (128-Pin TQFP and 84-Pin
MLCC Only)
The TBI is fully compliant with IEEE 802.3 clause 36. It
may be used as an alternative to the GMII in 1000Base-T
mode. The TBI mode is selected by setting the hardware con-
figuration pins MAC_IF_SEL[2:0] = 001.

The MAC drives this 125 MHz clock signal and should
be held low during autonegotiation or when operating
in modes other than 1000Base-T.
The MAC transmits data synchronized with
PMA_TX_CLK to the ET1011C for transmission on
the media-dependent (transformer) interface.
The ET1011C generates a 62.5 MHz clock to synchro-
nize receive data for the odd code group. This signal is
180 degrees out of phase from PMA_RX_CLK[1].

The ET1011C generates a 62.5 MHz clock to synchro-
nize receive data for the even code group. This signal
is 180 degrees out of phase from PMA_RX_CLK[0].
This signal indicates that COMMA has been detected.
