The model ACT4404N series performs the fr ont-end analog function of inputting and outputting data through a transformer to a MIL-STD-1553 or Macair data bus. The ACT4404N and ACT4440N can be considered a "Universal" Transceiver in that it is compatible with MIL-STD-1553A/B, Macai r (A-3818, A-4905, A-5232 and A-5690). Design of these transceivers reflects partic ular attention to active filt er performance. This results in low bit and word error rate with superior waveform purity and minimal zero crossover di stortion. The ACT4404N and ACT4440N active filter design has additional high frequency roll-off to provide the required Macair low harmonic distortion waveform without increasing the pulse delay characteristics significantly. Efficient transmitter electrical a nd thermal design provides low internal power diss ipation and heat rise at high and well as l ow duty cycles. An optional receiver input thres hold adjustment can be accomplished by the use of the ''External Threshold" terminals. TRANSMITTER The Transmitter section accepts bi-phase TTL data at the input and when coupled to the data bus with a 1:1 transformer the data bus signal produced is 7.0 Volts typical P-P at point A-A’ (See Figure 3 or 4). 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 "INHIBIT'' input provides for the removal of the transmitter output from the line. A logic ''1'' applied to the ''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 m eet Macair specificati ons 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. RECEIVER The Receiver section accepts bi-phase differen tial 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). The internal threshold is nominally set to detect data bus signals exceeding 1.05 Vp-p and reject signals less than 0.6 Vp-p when used with a 1:1 turns ratio transformer (See Figure 3 or 4 for transformer data and typical connection). This threshold setting can be held by grounding the appropriate pins or modified with the use of external resistors. A low level at the ''STROBE'' input inhibits the DATA and DATA outputs.
