The DP8392A Coaxial Transceiver Interface (CTI) is a coaxial cable line driver receiver for Ethernet Thin Ethernet (Cheapernet) type local area networks The CTI is connected between the coaxial cable and the Data Terminal Equipment (DTE) In Ethernet applications the transceiver is usually mounted within a dedicated enclosure and is connected to the DTE via a transceiver cable In Cheapernet applications the CTI is typically located within the DTE and connects to the DTE through isolation transformers only The CTI consists of a Receiver Transmitter Collision Detector and a Jabber Timer The Transmitter connects directly to a 50 ohm coaxial cable where it is used to drive the coax when transmitting During transmission a jabber timer is initiated to disable the CTI transmitter in the event of a longer than legal length data packet Collision Detection circuitry monitors the signals on the coax to determine the presence of colliding packets and signals the DTE in the event of a collision
