Signals
PCS_TBI_RCLKN
PCS TBI Interface RCLKN.
Output
See the denition for E1110_TBI_RCLKN. This signal is
also driven during test scan mode from
E1110_TBI_RCLKN.
PCS_TBI_RXD[9:0]
PCS TBI Interface Receive Data
Output
See the denition for E1110_TBI_RXD[9:0].
PCS_TBI_TXD[9:0]
PCS TBI Interface Transmit Data
Input
See the denition for E1110_TBI_TXD[9:0].
PCS_TBI_TCLK
PCS TBI Interface Transmit Clock
Input
See the denition for E1110_MII_TCLK.
3.8 PHY Interface Signals
The signals in this section are used to interface the E-1110 core to the
external PHY. Signal direction is from the perspective of the E-1110 core.
E1110_MII_TCLK
PHY GMII/TBI 125 MHz Transmit Clock
Input
In the MII mode, this clock input is an MII transmit clock
running at either 2.5 or 25 MHz. The MII transmit data is
synchronized and output with respect to this clock.
In the test scan mode, this clock is output on the
MII_TCLK pin for scan mode testing of the E-110 core.
E1110_PHY_TCLK
PHY Transmit Clock in GMII/TBI
Output
E1110_PHY_CLK is a GMII/TBI transmit 125 MHz clock
output signal. The MAC continuously drives this signal to
the PHY device. It is used to synchronize the data in the
1000BASE-T GMII mode or in the 1000BASE-SX/CX/LX
TBI mode.
