Des cription
RGMII Transmit Clock provides a 25 MHz or 2.5 MHz reference
clock with ± 50 ppm tolerance depending on speed. In RGMII
mode, TX_CLK is used as TXC.
RGMII Transmit Control. TX_EN is presented on the rising edge of
TX_CLK. In RGMII mode, TX_CTRL is used as TX_CTL.
A logical derivative of TX_EN and TX_ER is presented on the fall-
ing edge of TX_CLK.
RGMII Transmit Data. In RGMII mode, TXD[3:0] are used as
TD[3:0].
The transmit data nibble is presented on TXD[3:0] on the rising
edge of TX_CLK.
RGMII Receive Clock provides a 25 MHz or 2.5 MHz reference
clock with ± 50 ppm tolerance derived from the received data
stream depending on speed. In RGMII mode, RX_CLK is used as
RXC.
RGMII Receive Control. RX_DV is presented on the rising edge of
RX_CLK. In RGMII mode, RX_CTRL is used as RX_CTL.
A logical derivative of RX_DV and RX_ER is presented on the fall-
ing edge of RX_CLK.
RGMII Receive Data. In RGMII mode, RXD[3:0] are used as
RD[3:0].
The receive data nibble is presented on RXD[3:0] on the rising
edge of RX_CLK.
