Description

Media Dependent Interface[0].

In MDI configuration, MDI[0]± is used for the transmit pair. In MDIX

configuration, MDI[0]± is used for the receive pair.

Media Dependent Interface[1].

In MDI configuration, MDI[1]± is used for the receive pair. In MDIX

configuration, MDI[1]± is used for the transmit pair.

In 100BASE-FX mode, SIGDET indicates whether a signal is

detected by the fiber optic transceiver.

In 100BASE-TX/10BASE-T modes, this pin should not be left

floating. It should be tied either high or low.

Description

MDC is the clock reference for the serial management interface. A

continuous clock stream is not required (i.e., MDC can be stopped

when the MDC/MDIO master is not sending a command). The

maximum frequency supported is 8.33 MHz.

MDIO is the management data. MDIO is used to transfer manage-

ment data in and out of the device synchronously to MDC. This pin

requires a pull-up resistor in a range from 1.5 kohm to 10 kohm.
