REPEATEROPERATION
Repeater mode of operation allows a data word that has been
received by the HI-8581 to be placed directly into its FIFO for
transmission. Repeater operation is similar to normal receiver
operation. In normal operation, either byte of a received data
word may be read from the receiver latches first by use of SEL
input. During repeater operation however, the lower byte of the
data word must be read first. This is necessary because, as the
data is being read, it is also being loaded into the FIFO and the
transmitter FIFO is always loaded with the lower byte of the data
word first. Signal flow for repeater operation is shown in the
Timing Diagrams section.
LINEDRIVEROPERATION
Theline driver inthe HI-8581isdesignedtodirectlydrive theARINC
429 bus.
The two ARINC outputs (TXA(OUT) and TXB(OUT))
provide a differential voltage to produce a +10 volt One, a -10 volt
Zero, and a 0 volt Null.
Setting Control Register bit 13 to zero
causes a slope of 1.5
s on the ARINC outputs; a one in Control
Register bit 13 causes a slope of 10
resistor and capacitor and tested to be within ARINC requirements.
Noadditional hardware isrequired to controlthe slope.
s. Timing is set by on-chip
