Typical applicaTions
3V Cable Driver with Active Termination
Driving back-terminated cables on single supplies usually
results in very limited signal amplitude at the receiving
end of the cable. However, positive feedback can be used
to reduce the size of the series back termination resistor,
thereby decreasing the attenuation between the series
and shunt termination resistors while still maintaining
controlledoutputimpedancefromtheline-drivingamplifier.
Figure 3 shows the LT6210 using this “active termination”
scheme on a single 3V supply. The amplifier is AC-coupled
andinaninvertinggainconfigurationtomaximizetheinput
signal range. The gain from VIN to the receiving end of the
cable, VOUT, is set to –1. The effective impedance looking
into the amplifier circuit from the cable is 50Ω throughout
the usable bandwidth.
The response of the cable driver with a 1MHz sinusoid is
shown in Figure 4. The circuit is capable of transmitting
a 1.5VP-P undistorted sinusoid to the 50Ω termination
resistor and has a full signal 1VP-P bandwidth of 50MHz.
