General Description
The CT1990/1 Series is a monolithic implementation of the MIL-STD-1553B Bus Controller, Remote Terminal and Passive Monitor functions. All protocol functions of MIL-STD-1553B are incorporated and a number of options are included to improve flexibility. These features include programming of the status word, illegalizing specific commands and an independent loop back self-test which is initiated by the subsystem. This unit is directly compatible with all transceivers and microprocessor interfaces such as the CT1611 and CT1800 produced by Aeroflex Incorporated. Block Diagram (With Transformers)
