78Q8392L

The 78Q8392L Ethernet Transceiver is a low power BiCMOS coax line transmitter/receiver. The device includes analog transmit and receive buffers, a 10MHz on-board oscillator, timing logic for jabber and heartbeat functions, output drivers and bandgap reference, in addition to a current reference and collision detector.

This transceiver of the 78Q8392L provides the interface between the single-ended coaxial cable signals and the Manchester-encoded differential logic signals. Primary functional blocks include the receiver, transmitter, collision detection and jabber timer. This IC may be used in either internal or external MAU environments.

The 78Q8392L is available in 16-pin plastic and 28-pin PLCC packages.
