Pin Configuration and Functions

The DP83848x pins are classified into the following interface categories (each interface is described in the

sections that follow):

•

Serial Management Interface

•

MAC Data Interface

•

Clock Interface

•

LED Interface

•

Reset

•

Strap Options

•

10/100 Mb/s PMD Interface

•

Special Connections

•

Power Supply Pins

NOTE

Strapping pin option. See Section 4.8 for strap definitions.

All DP83848x signal pins are I/O cells regardless of the particular use. The definitions below define the

functionality of the I/O cells for each pin.

Strapping Pin (All strap pins have weak internal pullups or pulldowns. If the default strap

value is to be changed then an external 2.2-k

Ω resistor should be used. See Section 4.8 for

details.)
