FULLY DC-COUPLED TRANSMISSION LINE
The wide input common-mode range and high input impedance of
the ADA4830-1 and ADA4830-2 allow them to be used in fully
dc-coupled transmission line applications in which there may be a
significant discrepancy between voltage levels at the ground pins of
the driver and receiver. As long as the voltage difference between
reference levels at the transmitter and receiver is within the
common-mode range of the receiver, very little current flow
results, and no image degradation should be anticipated.
Figure 42 shows an example configuration of a completely dc-
coupled transmission using a low impedance differential driver.
