MIL-STD 1553 SINGLE & DUAL DATA BUS TRANSFORMERS
10/07
The Pascall P1200 Series of Data Bus Transformers is designed to satisfy
the requirements of MIL-STD-1553A/B (DEF. STAN. 00-18 (Part 2) /1) and
may be used in either the bus coupling or isolation configurations.
The Transformers are compatible with currently available transceivers and
integrated terminals, meeting all the electrical requirements of Manchester
II serial bi-phase data transmission including MACAIR specifications. They
are also designed to meet the requirements of MIL-T-21038 Grades 5 & 7 /
Class S / Life X.
3Kohms minimum impedance at -55ºC
Can be tested in accordance with BS9000
Available in both leaded and surface mount packages
Extended range giving wide choice of turns ratios
Upper operating temperature limit to +125ºC
