Description
GMII Mode:
Receive data [7:4] pins. These pins are
synchronously output on the rising edge of
RX_CLK.
RGMII Mode:
Not used. Leave unconnected.
GMII Mode:
Receive data [3:0] pins. These pins are
synchronously output on the rising edge of
RX_CLK.
RGMII Mode:
Multiplexed receive data. Bits[3:0] are
synchronously output on the rising edge of
RX_CLK and bits[7:4] on the falling edge of
RX_CLK.
Receive clock. Receive data is sourced from the
PHY synchronously on the rising edge of RX_CLK
and is the recovered clock from the media.
MAC
and can be set to a 2.5 V or
