DESCRIPTION
The Aeroflex Plainview CT1820 Bit Processor Unit (BPU) is an advanced Hybrid Microcircuit that provides the interface between a MIL-STD-1553 Transceiver such as CT3231M or CT3232M, and the subsystem internal parallel data bus. The unit can be employed as the mux bus interface for Remote Subsystems or Master Terminal Bus Controllers, thus providing a common interfacefor all systems communicating over the bus.
