Pin Description
MTXCLK
I
87
MII Transmit clock:
MTXCLK is a continuous uniformed clock source
driven by the external PHY. It provides the timing
reference for the signals MTXEN and MTXD.
MTXCLK should be either 25MHz or 2.5MHz clock.
MTXD[3:0]
O
92-89
MII Transmit Data:
This nibble byte width transmit data bus is synchronized
with MTXCLK. It should be latched by the external
PHY at the rising edge of MTXCLK. MTXD[0] is the
least significant bit.
MTXEN
O
93
MII Transmit enable:
It indicates that transmits activity to an external PHY. It
will be synchronized with MTXCLK.
MMDC
O
94
MII management reference clock.
It is the reference clock of MMDIO. Each data bit will
be latched at the MMDC rising edge.
