Description
The 84220 is a highly integrated Ethernet Transceiver for
twisted pair and fiber Ethernet applications. The 84220
can be configured for either 100 Mbps (100BaseFX or
100BaseTX) or 10 Mbps (10BaseT) Ethernet operation.
The 84220 consists of four (4) separate and independent
channels. Each channel consists of: 4B5B/Manchester
encoder, scrambler, transmitter with wave shaping and on-
chip filters, transmit output driver, receiver with adaptive
equalizer, filters, baseline wander correction, clock and
data recovery, descrambler, 4B5B/Manchester decoder,
and controller interface (MII or RMII).
The addition of internal output waveshaping circuitry and
on-chip filters eliminates the need for external filters

The 84220 can automatically configure itself for 100 or 10
Mbps and Full or Half Duplex operation, for each channel
independently,

on-chip
AutoNegotiation
The 84220 can access eleven 16-bit registers for each
channel through the Management Interface (MI) serial
port. These registers comply to Clause 22 of IEEE 802.3u
and contain configuration inputs, status outputs, and
device capabilities.
The 84220 is ideal as a media interface for 100BaseTX/
100BaseFX/10BaseT switching hubs, repeaters, routers,
bridges, and other multi port applications.
The 84220 is implemented in a low power CMOS
technology and operates with a 3.3V power supply.
