AT79C1020 Overview
This Layer 2 Switch provides an ideal solution for the design of unmanaged full wirespeed multi-port Gigabit Ethernet (GbE) switches. Each port suppor ts either 10/100/1000 Mbps data rate. Flow controls, back pressure in half-duplex mode and PAUSE frame in full-duplex mode are employed to solve the HOL (Head of Line) blocking.
