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

FEATURES
• Very low power consumption
• Compliant with Ethernet II, IEEE 802.3 10Base5 and 10Base2
• Integrates all transceiver functions except signal and power isolation
• Innovative design minimizes external components count and power consumption
• Jabber timer function integrated on chip
• Externally selectable CED heartbeat allows operation with IEEE 802.3 compatible repeaters
• Squelch circuitry at all inputs rejects noise
• Power-on reset and test modes
• Advanced BiCMOS process
