Design of these transceivers reflects particular attention to active filter performance.This results in low bit and word error rate with superior waveform purity and minimal zero crossover distortion. The ARX4435 series active filter design has addi- tional high frequency roll-off to pro- vide the required low harmonic distortion waveform without increas- ing the delay characteristics signifi- cantly. Efficient transmitter electrical and thermal design results in low internal power dissipation and temperature rise at high and low duty cycle. Transmitter The Transmitter section accepts complementary TTL data at the input, and when coupled to the data bus with a 1:1 transformer, isolated on the transceiver side with two 35 Ohm fault isolation resistors, and loaded by a 170 Ohm termination, the data bus signal produced is 20 volts nominal P-P at A-A’. (See Figure 5.) When both DA TA and DATA inputs are held low or high, the transmitter output impedance is low, and signal is “removed” from the line.
