MIL-STD-1553A/B Bus Transceiver

Aeroflex UTMC 

TRANSMITTER

The transmitter section accepts Manchester II biphase TTL data

and converts this data into differential phase-modulated current

drive. Transmitter current drivers are coupled to a MIL-STD-

1553 data bus via a transformer driven from the TXOUT and

TXOUT terminals. Transmitter output terminals’ non-

transmitting state is enabled by asserting TXIHB (logic “1”), or

by placing both TXIN and TXIN at the same logic level. Table

1, Transmit Operating Mode, lists the functions for the output

data in reference to the state of TXIHB. Figure 3 shows typical

transmitter waveforms.

RECEIVER

The receiver section accepts biphase differential data from a

MIL-STD-1553 data bus at its RXIN and RXIN inputs. The

receiver converts input data to biphase Manchester II TTL

format and is available for decoding at the RXOUT and RXOUT

terminals. The outputs RXOUT and RXOUT represent positive

and negative excursions (respectively) of the inputs RXIN and

RXIN. Figure 4 shows typical receiver output waveforms.

2. Transmitter output terminals are in the non-transmitting mode during

Off-time.

3. Transmitter output terminals are in the non-transmitting mode during

Off-time, independent of TXIHB status.
