Input

2.5 V

CMOS

Receive Data.

Bits [3:0] are clocked on the rising edge of RXC.
Bits [7:4] are clocked on the falling edge of RXC.

NOTE: Shares balls with RXD[3:0]_0 on the GMII

interface.

Receive Control.

RX_CTL is RX_DV on the rising edge of RXC and
a logical derivative of RX_DV and RERR on the
falling edge of RXC.

NOTE: RX_CTL shares the same balls as RX_DV

on the GMII interface.
