The receiver section of the BUS-
63100 series accepts phase-modula-
ted bipolar data from a MIL-STD-1553
Data Bus and produces TTL signal
data at its outputs: RX Data Out and
RX Data Out. These outputs repre-

The small size and different model
capabilities available with the
BUS-63100 series simplify engineer-
ing design, making it an excellent
choice for interfacing with any
MIL-STD-1553 system.
