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.
