The differential outputs are balanced and designed to drive long lengths of coaxial cable, stripline, or twisted pair transmission lines with characteristic impedances ranging from 50 ohms to 500 ohms. Differential transmission is superior to single-wire transmission as it nullifies the effects of ground shifts and noise signals, which appear as common-mode voltages on the transmission line. If the signal voltage at the end of the line is found to be of insufficient magnitude, the following circuit may be used at the recipient equipment end to boost the levels.

The described system utilizes differential signaling to enhance transmission quality over various cable types, ensuring minimal signal degradation over long distances. The balanced differential outputs are crucial for maintaining signal integrity, particularly in environments susceptible to electromagnetic interference (EMI). By employing differential transmission, the circuit effectively cancels out noise that may be induced along the transmission line, thus preserving the clarity of the transmitted signal.

In practical applications, when the signal voltage diminishes below acceptable levels at the receiving end, a signal amplification circuit can be implemented. This circuit typically comprises an operational amplifier (op-amp) configured in a non-inverting or inverting mode, depending on the desired gain characteristics. The op-amp should be selected based on its bandwidth and slew rate to ensure it can handle the frequency of the input signal without distortion.

Additionally, feedback resistors can be utilized to set the gain of the amplifier, allowing for precise control over the output signal levels. It is advisable to keep the impedance matching in mind, especially when interfacing with 50-ohm to 500-ohm transmission lines, to prevent reflections that could further degrade the signal quality.

Power supply considerations for the op-amp circuit are also essential; a dual power supply may be used to accommodate the positive and negative voltage swings of the differential signal. Proper decoupling capacitors should be included to filter out any noise from the power supply lines, ensuring stable operation of the amplifier.

Overall, the integration of a boosting circuit at the receiving end enhances the reliability of differential transmission, making it suitable for applications in telecommunications, data communication, and other fields where signal integrity is paramount.The differential outputs are balanced and are designed to drive long lengths of coaxial cable, strip line, or twisted pair transmission lines with characteristic impedances of 50 ohms to 500 ohms.
