AN2720SC Overview

Key Features

  • In a USB system, the PC acts as a host, which initiates all USB traffic
  • USB devices act as slaves, which respond to host requests
  • It is inherently incompatible to connect two PCs together via a simple USB cable, since a master (host) cannot talk to another master (host)
  • A master can talk only to one or more slave devices
  • The AN2720SC overcomes this “peer-to-peer” incompatibility by providing two USB devices, one for each PC
  • Two independent Serial Interface Engines (SIE) exchange data through a 2 kilobyte FIFO
  • Thus, USB data transmitted by one computer is made available to the other computer through the AN2720SC
  • The connection is full duplex– data can be transferred in both directions simultaneously
  • AN2720SC EZ-Link (AN2720SC)
