ML4642CR Datasheet PDF - Micro Linear Corporation

GENERAL DESCRIPTION
The ML4642 AUI Multiplexer contains all the necessary drivers/receivers and control logic to implement a 2 port MAU when used in conjuction with a transceiver chip which has a standard 802.3 AUI interface. In addition, the ML4642 is capable of operating in stand-alone mode where it interconnects two DTEs in the absence of a network MAU. Several ML4642s can be cascaded together to implement a 4 or 8 port MAU or stand-alone device.

FEATURES
■ IEEE 802.3 compliant AUI interfaces assure compatibility with any AUI ready devices
■ No crystal or clock input
■ On-chip Jabber logic, Collision Detection, and SQE test with enable/disable option
■ Selectable Loopback, Jabber, and SQE Test allows cascading of multiple chips to increase DTE port
