82562ET Architectural Overview
The 82562ET is a highly integrated Platform LAN Connect device that combines a 10BASE-T and
100BASE-TX physical layer interfaces. The 82562ET supports a single interface fully compliant
with the IEEE 802.3 standard.
The 8252ET is a 3.3 V device in a 48-pin Shrink Small Outline Package (SSOP). This document
describes the architecture of the device in all modes of operation.
Four pins, test Enable (TESTEN), Test Clock (ISOL_TCK), Test Input (ISOL_TI), and Test
Execute (ISOL_EX), define the general operation of the device.
