Introduction
This chapter contains a brief introduction to the L80227 10BASE-
T/100BASE-TX Ethernet Physical Layer Device (PHY). It contains the
following sections:
This manual describes the L80227 device. The device contains a single
PHY channel. The convention used in this manual is that device refers
to the IC, and channel refers to the PHY in the device.
The L80227 is a highly-integrated analog interface IC for twisted-pair
Ethernet applications and can be configured for either 100 Mbits/s
(100BASE-TX) or 10 Mbits/s (10BASE-T) Ethernet operation.
The PHY channel contains the following blocks:
