Figure 12: Lowpass Filter Topology
Figure 13: Design Equations
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 14 indicates the filter response.
Figure 14: Lowpass Response
Differential Line Driver With Load
Impedance Conversion
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 CLC5602’s
output capabilites. The single-ended input signal is
converted to a differential signal by the CLC5602. 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.
Figure 15: Differential Line Driver wtih
Load Impedance Conversion
Set up the CLC5602 as a difference amplifier:
Make the best use of the CLC5602’s output drive
capability as follows:
where R
eq
is the transformed value of the load imped-
ance, V
max
is the Output Voltage Range, and I
max
is the
maximum Output Current.
Match the line’s characteristic impedance:
Select the transformer so that it loads the line with a
value very near Z
o
over frequency range. The output
impedance of the CLC5602 also affects the match. With
an ideal transformer we obtain:
