• Manufacturer Part Number: 88E1111-XX-BAB-C000
• Description: Integrated 10/100/1000 Ultra Gigabit Ethernet Transceiver
• Manufacturer: MARVELL [Marvell Technology Group Ltd.]

Table 3:
The TBI interface supports 1000BASE-T mode of operation. The TBI interface uses the same pins as the GMII
interface. The MAC interface pins are 3.3V tolerant.

Des cription
TBI Transmit Clock. In TBI mode, GTX_CLK
is used as TBI_TXCLK. TBI_TXCLK is a 125
MHz transmit clock.
TBI_TXCLK provides a 125 MHz clock refer-
ence for TX_EN, TX_ER, and TXD[7:0].
TBI 62.5 MHz Receive Clock- even code
group. In TBI mode, TX_CLK is used as
RCLK1.
TBI Transmit Data. TXD[7:0] presents the
data byte to be transmitted onto the cable.
TXD[9:0] are synchronous to GTX_CLK.
Inputs TXD[7:4] should be tied low if not
used (e.g., RTBI mode).
TBI Transmit Data. In TBI mode, TX_EN is
used as TXD8.
TXD[9:0] are synchronous to GTX_CLK.
TBI Transmit Data. In TBI mode, TX_ER is
used as TXD9.
TXD[9:0] are synchronous to GTX_CLK.
TX_ER should be tied low if not used (e.g.,
RTBI mode).
TBI 62.5 MHz Receive Clock- odd code
group. In the TBI mode, RX_CLK is used
as RCLK0.
TBI Receive Data code group [7:0]. In the
TBI mode, RXD[7:0] present the data byte to
be transmitted to the MAC. Symbols
received on the cable are decoded and pre-
sented on RXD[7:0].
RXD[7:0] are synchronous to RCLK0 and
RCLK1.
TBI Receive Data code group bit 8. In the
TBI mode, RX_DV is used as RXD8.
RXD[9:0] are synchronous to RCLK0 and
RCLK1.
