sec-
tion for Belden 8281, and can be scaled as stated above to
estimate maximum cable lengths and data rates for UTP.
Category 5 UTP has a characteristic impedance of approxi-
mately 100
. The CLC005 in Figure 13 is used to drive the
twisted pair AC-coupled with a series 0.1 μF capacitor and a
50
resistor in each differential output. The CLC012 Adap-
tive Equalizer requires 800 mV
from the transmit side of
the cable. A voltage divider is necessary to scale the voltage
to the required level at the input of the CLC012. This resistor
network also provides the correct impedance match for
twisted pair.
For Category 5 UTP, the approximate AEC voltage per
length is 3.75 mV/m (see
Block Description
). The CLC005
provides a trim adjust for fine tuning the output signal with
the resistor R. Refer to the CLC005 datasheet for tuning
directions.
