DESCRIPTION

The NE83Q92 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). The transmitter output connects directly to a doubly terminated 50? cable, while the receiver output, collision detector output and transmitter input are connected to the DTE through isolation transformers.

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 (N & A options)

? Optimal implementation can use 1 Watt DC-DC converter and reduces external part count by not requiring external pull-down resistors

? High efficiency AUI drivers automatically power-down under idle conditions to minimize current consumption

? Automatically disables AUI drivers when no coaxial cable is connected, allowing hard-wiring 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, 16-pin SOL and both 20- 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
