GENERAL DESCRIPTION

The ML4644 AUI Multiplexer contains all the necessary drivers/receivers and control logic to implement a 4 port MAU when used in conjuction with a transceiver chip which has a standard 802.3 AUI interface. Several ML4644s can be cascaded together to implement an 8 or 12 port MAU or standalone device.

FEATURES

■ IEEE 802.3 compliant AUI interfaces assure compatibility with any AUI ready devices.

■ On-chip Jabber logic, Collision Detection, and SQE test with enable/disable option.

■ Selectable SQE Test

■ Selectable loopback

■ Ten network status LED outputs.
