capacitive coupling

Electronics
The intentional or fortuitous transfer of energy within an electrical network by capacitance between circuit nodes.

Surgery
A potential endoscopic electrosurgical hazard, which occurs when electrical current is transferred from one conductor —e.g., an active electrode surrounded by insulation—into adjacent conductive materials—e.g., a trocar or tissue. The risk of tissue damage can be reduced by using low-power, low-voltage settings with intermittent rather than prolonged bursts, and by not operating near metal or conductive objects in the operative field.

The device automatically optimizes its transfer function based on the bit rate and cable length in order to minimize the inter-symbol interference (ISI) jitter caused by the cable as well as remove the DC offset components introduced with the pathological test pattern and AC coupling in systems.
The chipset features AC coupling support, DC balance and pre-emphasis that will support up to 10 meters of cabling length.
This feature bridges any gap between the output voltage range of the component before the ADC and the ADC input range, eliminating the need for ac coupling.
