3.6 Obtaining IEEE Addresses

Each node of a Local Area Network has

a unique address for the media access

control (MAC). This makes it possible

for that particular node to have unique

identity for data communication. This

address, known as the IEEE physical

address, consists of 48 bits of data. This

address is assigned to a LAN physical

interface node by the manufacturer of

the network interface card.

To ensure uniqueness of the address, 24

bits of out of the 48 bits of the physical

address are assigned to the manufacturer

by the IEEE standards committee. This

24 bit address is known as

Organizationally Unique Identifier

(OUI).

The remaining 24 bits of the address are

assigned by the manufacturer. For

further information and an application

for an OUI, please contact the IEEE at

the following address:

Adapter boards shipped as part of

Crystal’s CS8920 Evaluation Kit are

programmed with an IEEE Physical

Address obtained from an allotment

assigned to Crystal Semiconductor Corp.

by the IEEE.
