Pin Function
3.3V, 2.5V, or 1.8V digital VDD_IO
GMII mode:
GMII TX_ER (Transmit Error) input
MII mode:
MII TX_ER (Transmit Error) input
If the GMII/MII MAC does not provide the TX_ER output signal, this pin should be
tied low.
GMII mode:
GMII GTX_CLK (Transmit Reference Clock) input
GMII mode:
GMII TX_EN (Transmit Enable) input
MII mode:
MII TX_EN (Transmit Enable) input
GMII mode:
GMII RXD7 (Receive Data 7) output
MII mode:
This pin is not used and is driven low.
GMII mode:
GMII RXD6 (Receive Data 6) output
MII mode:
This pin is not used and is driven low.
1.2V digital VDD
GMII mode:
GMII RXD5 (Receive Data 5) output
MII mode:
This pin is not used and is driven low.
GMII mode:
GMII RXD4 (Receive Data 4) output
MII mode:
This pin is not used and is driven low.
GMII mode:
GMII RXD3 (Receive Data 3) output
MII mode:
MII RXD3 (Receive Data 3) output
Config mode:
The voltage on this pin is sampled and latched during the
power-up/reset process to determine the value of MODE3. See
the “Strapping Options” section for details.
3.3V, 2.5V, or 1.8V digital VDD_IO
GMII mode:
GMII RXD2 (Receive Data 2) output
MII mode:
MII RXD2 (Receive Data 2) output
Config mode:
The voltage on this pin is sampled and latched during the
power-up/reset process to determine the value of MODE2. See
the “Strapping Options” section for details.
1.2V digital VDD
GMII mode:
GMII RXD1 (Receive Data 1) output
MII mode:
MII RXD1 (Receive Data 1) output
Config mode:
The voltage on this pin is sampled and latched during the
power-up/reset process to determine the value of MODE1. See
the “Strapping Options” section for details.
GMII mode:
GMII RXD0 (Receive Data 0) output
MII mode:
MII RXD0 (Receive Data 0) output
Config mode:
The voltage on this pin is sampled and latched during the
power-up/reset process to determine the value of MODE0.
See the “Strapping Options” section for details.
GMII mode:
GMII RX_DV (Receive Data Valid) output
MII mode:
MII RX_DV (Receive Data Valid) output
Config mode:
The voltage on this pin is sampled and latched during the
power-up/reset process to establish the value of CLK125_EN.
See the “Strapping Options” section for details.
3.3V, 2.5V, or 1.8V digital VDD_IO
GMII mode:
