Differential Line Driver With Load Impedance Conver-
sion
The circuit shown in the Typical Application schematic on
the front page and in Figure 15, operates as a differential line
driver. The transformer converts the load impedance to a
value that best matches the CLC5622’s output capabilities.
The single-ended input signal is converted to a differential
signal by the CLC5622. The line’s characteristic impedance
is matched at both the input and the output. The schematic
shows Unshielded Twisted Pair for the transmission line;
other types of lines can also be driven.
Set up the CLC5622 as a difference amplifier:
