The BUS-63100 Series offers complete transmitter and receiver
pairs packaged in either single or dual redundant form which are
designed for use in any MIL-STD-1553 application.
Figure 1 shows a BUS-63100 Series transceiver connected to a
MIL-STD 1553 Data Bus. Once transformer isolated, coupling to
a MIL-STD-1553 Data Bus can be either short stub (direct) or
long (transformer). Figure 2 shows the different configurations
and lists the recommended DDC transformer bus product for use
with each model.
DDC’s BUS-63100 Series of transceivers offer a wide range of
capabilities (on selected models), which include power supply
voltage levels, packaging configurations, Smiths or Harris type
encode/decoder direct compatibility, and internal (pre-set)
and/or external (adjustable) threshold levels. The capabilities of
the different models are described in the paragraphs which fol-
low and are summarized in TABLE 1.
POWER SUPPLY VOLTAGES
Power supply voltage requirements on the BUS-63102 and
BUS-63104 are met over a range from ±12 V to ±15 V. All mod-
els operate with either -12 V or -15 V supplies. All models
require a + 5 V supply. Refer to TABLE 1.
Single transceivers, BUS-63102 and BUS-63104 are packaged
in 24 pin square packages, all other single transceivers are
packaged in 24 pin DDIP. Dual transceivers are packaged in 36
BUS-63105, BUS-63107, BUS-63125 and BUS-63127 are
directly compatible to Harris 15530 type Encoder/Decoders. All
other transceivers are directly compatible to Smiths type.
Transceivers which are directly comparible with one type can be
converted for use with the other by simply switching the output
lines, RX Data and RX Data, and inverting their signals by
means of external inverting gates.
All transceivers conform fully to MIL-STD-1553 requirements.
Additionally, BUS-63102 conforms to MACAIR standards, pro-
ducing sinusoidal waveforms at 1 MHz.
All models offer internal (factory preset) threshold levels.
Additionally, BUS-63102 and BUS-63104 offer externally set
threshold levels. These external threshold levels are adjustable
from 0 V to 2 V, with the use of two external 10 KOhm poten-
tiometers; see FIGURE 5.
