MIL-STD-1553 is a DOD Military (MIL) Standard (STD), which defines
both the Mechanical, Electrical, and Functional characteristics.
MIL-STD-1553 uses Manchester II Bi-Phase L bit encoding. Manchester Encoding translates a '1' into a low to high transition [01], and a '0' is translated into a high to low transition [10]. Also called Biphase Code.
Manchester code: A code in which the data and clock signals are combined to form a single self synchronizing data stream, each encoded bit contains a transition at the midpoint of a bit period. The direction of transition determines whether the bit is a “0” or a “1,” and the first half is the true bit true bit value. This contrasts with non-return-to zero.
