Figure 8. Transmission Response of 300 m of
Category 5 Cable
The feedback network is between Pins 6 and 5 and from Pin 5
to ground. C1 and R
F
create a corner frequency of about 800 kHz.
The gain increases to provide about 15 dB of boost at 8 MHz.
The response of this circuit is shown in Figure 9.

Figure 9. Frequency Response of Equalizer Circuit
It is difficult to come up with the exact component values via
strictly mathematical means, because the equations for the cable
attenuation are approximate and have functions that are not
simply related to the responses of RC networks. The method
used in this design was to approximate the required response via
graphical means from the frequency response, and then select
components that would approximate this response. The circuit
was then built and measured, and finally adjusted to obtain an
acceptable response—in this case flat to 9 MHz to within
approximately 1 dB. (See Figure 10.)

Figure 10. Combined Response of Cable Plus Equalizer
Output Offset/Level Translator
The circuit in Figure 6 has the reference input (Pin 4) tied to
ground, which produces a ground-referenced output signal. If it is
desired to offset the output voltage from ground, the REF input
can be used. (See Figure 11). The level V
OFFSET
appears at the
output with unity gain.

Figure 11. The voltage applied to Pin 4 adds to the unity-
gain output voltage produced by V
IN
.
If the circuit has a gain higher than unity, the gain has to be
factored in. If R
G
is connected to ground, the voltage applied to
REF will be multiplied by the gain of the circuit and appear at
the output; just like a noninverting conventional op amp, This
situation is not always desirable and one may want V
OFFSET
to
appear at the output with unity gain.
One way to accomplish this is to drive both REF and R
G
with
the desired offset signal. (See Figure 12.) Superposition can be
used to solve this circuit. First break the connection between
V
OFFSET
and R
G
. With R
G
grounded the gain from Pin 4 to
V
OUT
will be 1 + R
F
/R
G
. With Pin 4 grounded, the gain though
R
G
to V
OUT
is –R
F
/R
G
. The sum of these is +1. If V
REF
is delivered
from a low-impedance source, this will work fine. However, if
the delivered offset voltage is derived from a high-impedance
source, like a voltage divider, its impedance will affect the gain
equation. This makes the circuit more complicated as it creates
an interaction between the gain and offset voltage.
