DESCRIPTION
When both DATA and DATA inputs are held low or high, the
transmitter output becomes a high impedance and is “removed”
from the line. In addition, an overriding “TX INHIBIT" input
provides for the removal of the transmitter output from the line. A
logic “1” applied to the “TX INHIBIT” takes priority over the
condition of the data inputs and disables the transmitter (See
Transmitter Logic Waveforms - Figure 3).
The transmitter utilizes an active filter to suppress harmonics
above 1 MHz to meet MacAir specifications A-3818, A-4905,
A-5232 and A-5690. The transmitter may be safely operated for
an indefinite period at 100% duty cycle into a data bus short
circuit.
The transmitter output level is controlled by an external DC
Voltage of 0VDC to 10VDC for full output, regardless of the bus
type selected. External ceramic coupling capacitors, with 10KΩ
resistors connected in parallel to the capacitor (low ESR), are
needed to connect the transmitter outputs to the primary of the
coupling transformer.
The main difference between H009 transmitter operation and
MacAir/1553/1760 transmitter operation is the Inhibit function
(TX INHIBIT A / TX INHIBIT B). In H009 operation, when both
the DATA and DATA transmitter inputs are held low or high, the
transmitter output impedance is low, and there is no transmitter
output signal. This function is used to terminate the bus, for a
period of time, in a H009 system. When the TX INHIBIT is pulled
up to 5VDC or left open circuited, the transmitter output goes into
a high impedance state, effectively removing it from the bus.
Aeroflex Plainview transceiver model ACT4462D is the first
transceiver to combine H009 Bus and MacAir / 1553 / 1760 Bus
operation in a Variable Amplitude Dual Channel, pin selectable,
hybrid. In addition to pin selectable bus operation the transceiver
allows the user to externally set the receiver threshold, for either
channel, to optimize system performance. Two pins, per channel,
are brought out for external threshold adjustment, and, with the
addition of a resistor from each pin to ground the threshold can be
tailored for each channel separately. This Dual Channel, Variable
Amplitude, Pin Selectable H009 or MacAir/1553/1760
Transceiver allows the user to stock one component when the
system has both a H009 Bus as well as a MacAir/1553/1760 Bus.
It should also appeal to H009/MacAir/1553/1760 test equipment
manufacturers.
TRANSMITTER
H009 OPERATION
When the 1553/H009 select pin is tied to 5VDC, the transmitter
is in H009 operation and accepts bi-phase TTL data at the input
and when coupled to the data bus with a 1:1 transformer, isolated
on the transceiver side with two 34 Ohm bus terminating resistors,
with the bus terminated by a 170 Ohm resistor the data bus signal
produced is 21Vp-p typical at A-A' (See Figure 9). When both
DATA and DATA inputs are held low or high, the transmitter
output becomes a low impedance and signal is “removed” from
the line. In addition, an overriding “TX INHIBIT" input returns
the output to a high impedance state. A logic “1” applied to the
“TX INHIBIT” takes priority over the condition of the data inputs
and disables the transmitter (See Transmitter Logic Waveforms -
Figure 1). The transmitter utilizes an active filter to suppress
harmonics above 1 MHz to meet H009 specifications. The
transmitter may be safely operated for an indefinite period at
100% duty cycle into a data bus short circuit.
RECEIVER
The Receiver section accepts bi-phase differential data at the
input and produces two TTL signals at the output. The outputs are
DATA and DATA, and represent positive and negative excursions
of the input beyond a pre-determined threshold (See Receiver
Logic Waveforms
- Figure 2 and 4). Since H009 and
MacAIR / 1553 / 1760 OPERATION
When the 1553/H009 select pin is left open circuit, the
MacAir/1553/1760 bus thresholds are usually different, the
receiver threshold levels for both channels can be set, for either
bus operation, with the Threshold adjust pins. Grounding the
DATA and DATA threshold adjust pins, for channel A or B, will
set normal 1553 threshold levels of about 0.9Vp-p at 1MHz. By
adding a resistor from each threshold pin to ground the receiver
threshold level can be increased from normal 1553 levels to
normal H009 levels of about 2Vp-p at 1Mhz, or set anywhere in
between.
transmitter is in the MacAir /1553 /1760 operation and accepts
bi-phase TTL data at the input and when coupled to the data bus
with a 1:1 transformer, isolated on the data bus side with two 55
Ohm fault isolation resistors, and loaded by two 70 Ohm
terminations plus additional receivers, the data bus signal
produced is 7.0Vp-p minimum at A-A’ (See Figure 11 and 12).
