Web29 Dec 2024 · The parallel termination resistor is Zpt. Figure 2. Parallel Terminated Line “In the case of the parallel terminator, we are delivering the voltage waveforms to the receiver. The job of parallel terminators is to take the energy out of the circuit so we don’t get reflections,” Ritchey explains. “Once the signal has reached the pin we ... Web17 Oct 2024 · The advantage of the split termination is that it provides a low impedance path to ground for common mode noise. Differential signals see the termination resistor as the input impedance of the amplifier. Common mode signals (usually noise) do not create any voltage difference across the single termination resistor in the unsplit version.
