Single Supply Lowpass Filter  
Figures 14 and 15 illustrate a lowpass filter and design  
equations. The circuit operates from a single supply of  
+5V. The voltage divider biases the non-inverting input to  
2.5V. And the input is AC coupled to prevent the need for  
level shifting the input signal at the source. Use the

Differential Line Driver With Load  
Impedance Conversion  
The circuit shown in the Typical Application schematic  
on the front page and in Figure 17, operates as a  
differential line driver. The transformer converts the load  
impedance to a value that best matches the CLC5623’s  
output capabilities. The single-ended input signal is  
converted to a differential signal by the CLC5623. 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.
