phenomenon, accentuated at high frequencies, is unavoidable and intrinsic to the circuit
itself.
Nevertheless, the PCB layout also has an effect on the crosstalk level. Capacitive coupling
between signal wires, distance between critical signal nodes and power supply bypassing
are the most significant factors.
Figure 65. Crosstalk vs. frequency: A
shows an example of crosstalk from one amplifier to a second amplifier. This
