DESCRIPTION The 78Q8392L/A03 Ethernet Transceiver is a replacement for the 78Q8392L/A02 coax line transmitter/receiver. Only a single resistor value change is required for upgrading an existing 78Q8392L/A02 design to the 78Q8392L/A03. The device includes analog transmit and receive buffers, a ...

FUNCTIONAL DESCRIPTION The 78Q8392L/A03 incorporates six basic functions of the Ethernet Transceiver, including receiving, transmitting, collision signaling, collision detection, jabber timing, and the heartbeat function. Refer to Figure 1 for a general system block diagram. RECEIVER FUNCTIONS The receiver senses ...
