... The receiver section of each channel converts the 1553 bus bi-phase data to complementary CMOS / TTL data suitable for inputting to a Manchester decoder. Each receiver has a separate enable input which can be used to force the output of the receiver to a logic 0. The transmitter outputs and receiver inputs for each channel are brought out to separate sets of pins ...

... In a transformer coupled interface (see Figure 3), the transceiver is connected to a 1:1.79 isolation transformer TXA B / are ei- which in turn is connected to a 1:1.4 coupling transformer. The transformer coupled method also requires two coupling resistors equal to 75% of the bus characteristic impedence (Zo) between the coupling transformer and the bus. ...
