DESCRIPTION
The NE83C92 is a low power BiCMOS coaxial transceiver interface (CTI) for Ethernet (10base5) and Thin Ethernet (10base2) local area networks. The CTI is connected between the coaxial cable and the Data Terminal Equipment (DTE) and consists of a receiver, transmitter, receive-mode collision detector, heartbeat generator and jabber timer (see Block Diagram).

FEATURES
• Fully compliant with Ethernet II, IEEE 802.3 10BASE-5 and 10BASE-2, and ISO 8802/3 interface specifications
• 100% drop-in compatible with industry standard 8392 sockets
• Optimal implementation can use 1 Watt DC-DC converter and reduces external part count (local/integrated MAU requires no external pull-down resistors).
• High efficiency AUI drivers automatically power-down under idle conditions to minimize current consumption
• Automatically disabling AUI drivers when disconnecting coax cable, allowing hardwiring of AUI connection and local/integrated CTI connection
• Smart squelch on data inputs eliminates false activations
• Advanced BiCMOS process for extremely low power operation
• Available in 16-pin DIP, and 28-pin PLCC packages
• Expanded version (NE83Q93) with 5 LED status drivers is available for repeater and advanced system applications
• Full ESD protection
• Power-on reset prevents glitches on coaxial cable during power-up
