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.
