A block diagram of a typical application is shown in Figure 1 The 82503 Dual Serial Transceiver is a high-inte-
gration CMOS device designed to simplify interfacing industry standard Ethernet LAN Controllers to IEEE
802 3 local area network applications (10BASE5 10BASE2 and 10BASE-T) The component supports both
an attachment unit interface (AUI) and a Twisted Pair Ethernet interface (TPE) It allows OEMs to design a
state-of-the-art media interface that is jumperless and fully automatic The 82503 includes on-chip AUI and
TPE drivers and receivers it offers designers a cost-effective integrated solution for interfacing LAN control-
lers to the wire medium
