description and applications the military data bus specification, mil-std-1553, has brought about the need for versatile pulse transformers that meet all the electrical requirements of manchester ii serial bi-phase data transmission. the b-2200/2300/3200 series of transformers provide the turns ratio con- figurations, component isolation, and common mode rejection ratio characteristics necessary for mil-std-1553a and b compliance. the step-up and step-down ratios that are available with the b- 2200/2300/3200 series complement ddc?s entire mil-std-1553 product line. these transformers are low-profile, modular units that are multi- tapped to accommodate existing system configurations. encapsulated in accordance with mil-prf-21038, their sn63 solder-dipped copper-clad steel leads conveniently accommodate printed circuit board mounting. sinusoidal or trapezoidal waveforms are accurately processed, making the b-2200/2300/3200 series of transformers an excellent choice for any mil- std-1553a or b application. features fully qualified to desc specification no. 21038/27 ? for use with mil-std-1553a and b, macair a-5690, a-5232, and a-4905 low-profile -55 c to +130 c operating temperature range built and tested to mil-prf-21038 and mil-std-202 listed on qpl-21038-31 qualification validated annually n : 1 e out e = 10 v rms at 1 mhz in calc: cmr = 20 log (see note) e in e out e in 1 : n e out (see note) e = 250 khz square wave, 27.0 volts peak-to-peak with in a rise and fall time no greater than 100 ns. calc : droop = x 100%.
