Description

The 80220/80221 are highly integrated analog interface

IC's for twisted pair Ethernet applications. The 80220/

80221 can be configured for either 100 Mbps (100Base-

TX) or 10 Mbps (10Base-T) Ethernet operation. The

80220 is packaged in a 44L package, while the 80221 is

packaged in a 64L package and contains a few more

features.

The 80220/80221 consist of 4B5B/Manchester encoder/

decoder, scrambler/descrambler, 100Base-TX/10Base-T

twisted pair transmitter with wave shaping and output

driver, 100Base-TX/10Base-T twisted pair receiver with

on chip equalizer and baseline wander correction, clock

and data recovery, AutoNegotiation, controller interface

(MII), and serial port (MI).

The addition of internal output waveshaping circuitry and

on-chip filters eliminates the need for external filters nor-

mally required in 100Base-TX and 10Base-T applications.

The 80220/80221 can automatically configure itself for

100 or 10 Mbps and Full or Half Duplex operation with the

on-chip AutoNegotiation algorithm.

The 80220/80221 can access eleven 16-bit registers though

the Management Interface (MI) serial port. These registers

contain configuration inputs, status outputs, and device

capabilities.

The 80220/80221 are ideal as media interfaces for

100Base-TX/10Base-T adapter cards, motherboards, re-

peaters, switching hubs, and external PHY's.
