78Q8392LA03-28CH/F

The 78Q8392LA03-28CH/F is a low power Ethernet coaxial transceiver in 28 pin PLCC package. This Ethernet transceiver is a replacement for the SSI/TDK/Teridian 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 analogue 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 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.
