INTERFACE TO MIL-STD-1553 BUS
Interfacing the BUS-65153 to a MIL-STD-1553 bus requires a
pair of pulse transformers. These transformers, or QPL equiva-
lents, are available from Beta Transformer Technology
Corporation, a subsidiary of DDC. The BUS-65153 hybrid and
Beta Transformers may be wired for either direct coupled or stub
coupled configurations. The recommended transformer for each
of the BUS-65153 transceiver options is listed in TABLE 4.
The interface between a BUS-65153 and a MIL-STD-1553 bus
is illustrated in FIGURE 15.Notes for TABLE 4:
Notes for TABLE 4:
(1)Shown for one of two redundant buses that interface to the BUS-
65153 hybrid.
(2)Transmitted voltage level on 1553 bus is 6 Vp-p min, 7 Vp-p nomi-
nal, 9 Vp-p max.
(3)Required tolerance on isolation resistors is 2%. Instantaneous power
dissipation (when transmitting) is approximately 0.5 W (typ), 0.8 W
(max).
(4)Transformer pin numbering is correct for DDC BUS-25679 or BUS-
29854 transformer. For the Beta transformer (e.g., B-2203) or the QPL-
21038-31 transformer (e.g., M21038/27-02), the winding sense and
turns ratio are mechanically the same, but the pin numbering is
reversed. Therefore, it is necessary to reverse pins 8 and 4 or pins 7
and 5 in the diagram for the Beta or QPL transformers.
(5) The B-2204, B-2388, and B-2344 transformers have a slightly differ-
ent turns ratio on the direct coupled taps then the turns ratio of the
BUS-29854 direct coupled taps. They do, however, have the same
transformer coupled ratio. For transformer coupled applications, either
transformer may be used. The transceiver in the BU-65170X2 and the
BU-61580X2 was designed to work with a 1:0.83 ratio for direct cou-
pled applications. For direct coupled applications, the 1.20:1 turns ratio
is recommended, but the 1.25:1 may be used. The 1.25:1 turns ratio
will result in a slightly lower transmitter amplitude. (Approximately 3.6%
lower) and a slight shift in the ACE's receiver threshold.
