Single Supply Cable Driver
The typical application shown below shows one of the
CLC5623 amplifiers driving 10m of 75
coaxial cable.
The CLC5623 is set for a gain of +2V/V to compensate
for the divide-by-two voltage drop at V
o
.

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.

This example illustrates a lowpass filter with Q = 0.707
and corner frequency f
c
= 10MHz. A Q of 0.707 was
chosen to achieve a maximally flat, Butterworth
response. Figure 16 indicates the filter response.

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.
