MIL-STD-1553A/B Bus Transceiver

Aeroflex UTMC 

DATA BUS INTERFACE

The designer can connect the UT63M1XX to the data bus via a

short-stub (direct-coupling) connection or a long-stub

(transformer-coupling) connection. Use a short-stub connection

when the distance from the isolation transformer to the data bus

does not exceed a one-foot maximum. Use a long-stub

connection when the distance from the isolation transformer

exceeds the one-foot maximum and is less than twenty-five feet.

Figure 5 shows various examples of bus coupling

configurations. The UT63M1XX series transceivers are

designed to function with MIL-STD-1553A and 1553B

compatible transformers.

RECOMMENDED THERMAL PROTECTION

All packages, single and dual, should mount to or contact a heat

removal rail located in the printed circuit board. To insure proper

heat transfer between the package and the heat removal rail, use

a thermally conductive material between the package and the

heat removal rail. Use a material such as Mereco XLN-589 or

equivalent to insure heat transfer between the package and heat

removal rail.
