GENERAL DESCRIPTION

The Am7996 IEEE 802.3/Ethernet/Cheapernet Transceiver supports Ethernet Version 2, IEEE 802.3 10BASE-5 and IEEE 802.3 10BASE-2—Cheapernet) transceiver applications. Transmit, receive, and collision detect functions at the coaxial media interface to the data terminal equipment (DTE) are all performed by this single device.

DISTINCTIVE CHARACTERISTICS

■ Compatible with Ethernet Version 2 and IEEE 802.3 10BASE-5 and10BASE-2 specifications

■ Pin-selectable SQE Test (heartbeat) option

■ Internal jabber controller prevents excessive transmission time

■ Noise rejection filter ensures that only valid data is transmitted onto the network

■ Collision detection on both transmit and receive data

■ Collision detect threshold levels adjustable for other networking applications
