2.12.3.1

Ethernet management interface 1 DC electrical characteristics

The Ethernet management interface 1 is defined to operate at a supply voltage of 3.3 V. The DC electrical characteristics for the

Ethernet management interface is provided in this table.

The Ethernet management interface 1 is defined to operate at a supply voltage of 3.3 V. The DC electrical characteristics for the

Ethernet management interface 1 is provided in Table 37.

2.12.3.2

Ethernet management interface 2 DC electrical characteristics

Ethernet management interface 2 pins function as open drain I/Os. The interface conforms to 1.2 V nominal voltage levels.

LVDD must be powered to use this interface. The DC electrical characteristics for EMI2_MDIO and EMI2_MDC are provided

in this section.
