TABLE 65. BTTC TRANSFORMERS FOR USE WITH ENHANCED MINI-ACE
Notes:
1. For the BU-6XXXXX4 versions of the Enhanced Mini-ACE, which include the McAir-compatible transceivers, only the B-3818 or B-3819
transformers (shown in
bold
in the table) may be used.
2. For the BU-6XXXXX3 versions of the Enhanced Mini-ACE with -1553B transceivers, any of the transformers listed in the table may be used.
TRANSFORMERS
In selecting isolation transformers to be used with the PCI
Enhanced Mini-ACE, there is a limitation on the maximum
amount of leakage inductance.If this limit is exceeded, the trans-
mitter rise and fall times may increase, possibly causing the bus
amplitude to fall below the minimum level required by MIL-STD-
1553. In addition, an excessive leakage inductance imbalance
may result in a transmitter dynamic offset that exceeds 1553
specifications.
The maximum allowable leakage inductance is 6.0uH.It is meas-
ured as follows:
Defining the side of the transformer that connects to the PCI
Enhanced Mini-ACE as the "primary" winding, if one side of the
primary is shorted to the primary center-tap, the inductance
should be measured across the "secondary" (stud side) winding.
This inductance must be less than 6.0uH. Similarly, if the other
side of the primary is shorted to the primary center-tap, the
inductance measured across the "secondary" (stub side) wind-
ing must also be less than 6.0uH.
The difference between those two measurement is the "differen-
tial" leakage inductance.This value must be less than 1.0uH.
Beta Transformer Technology Corporation (BTTC), a subsidiary
of DDC, manufactures transformers in a variety of mechanical
configurations with the required turns ratios of 1:2.5 direct cou-
pled, and 1:1.79 transformer coupled. TABLE 65 provides a list-
ing of many of these transformers.
