CT1990/1 Series MIL-STD-1553B Remote Terminal, Bus Controller, or Passive Monitor Hybrid with Status Word Control Features • Performs the Complete Dual-Redundant Remote Terminal, Bus Controller Protocol and Passive Monitor Functions of MIL-STD-1553B • Automated Self-Test Functions • Allows setting of the Message Error Bit on illegal commands • Provides programmable control over Terminal Flag and Subsystem Flag Status Bits • MIL-PRF-38534 Compliant Circuits Available • 50 mw Typical Power Consumption • Small Size • Available in Ceramic Plug-in Package Configuration CIRCUIT TECHNOLOGY • Compatible with all ACT Driver/Receiver Units • 5V DC Operation • Full Military (-55°C to +125°C) Temperature Range • DESC SMD# 5962–94775: Released CT1990, Pending CT1991 1 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.
