Transmitter Channel

Unit (TCU)

Overview

Outputs

The TCU is composed of three ARINC transmit channels and has per channel:

• a parallel to serial converter to translate the messages into two serial signals,

• a FIFO memory to store eight 32-bit ARINC messages,

• a control logic to synchronize the message transmitter (parity, gap, speed...).

Each transmitter channel has two output lines, Transmit line High (TXiH) and Transmit

line Low (TXiL) which are not directly compatible with the bipolar modulated ARINC line.

These RZ format lines should be translated by an outside device into ARINC three-level

state signal according to Figure 15.
