The RCU is composed of 8 ARINC receiver channels and has per channel:
•
•
•
•
Each receiver channel has two input lines, receiving line high (RxiH) and receiving line
low (RXiL) which are not directly compatible with the bipolar modulated ARINC line. This
ARINC three-level state signals (“HIGH”, “NULL”, “LOW”) should be demultiplexed to
generate the two RZ lines according to Figure 8.
Each channel has a test mode in which the input signals (RXiH, RXiL), are internally
connected to the third Transmit Channel Lines. This selection is done by programming
the Test bit in the receiver control register (see “Register Description” on page 17)
except this difference, the TS68C429A behaves exactly the same manner in the two
modes. The receiver channel block diagram is given in Figure 9.
ARINC signals being asynchronous, the RCU first rebuilds the received clock in order to
transfer the data within the shift-register and when the Gap-controller has detected the
end of the message, tests the message validity according to the criteria listed hereafter.
a serial to parallel converter to translate the two serial signals in two 16-bit words.
a memory to store the authorized labels,
a control logic to check the validity of the received message.
a buffer to keep the last valid received message.
