100MHz Video Line Driver

Video Distribution Amplifier

In this broadcast quality circuit, the EL2006C FET input

amplifier provides a very high input impedance so that it

may be used with a wide variety of signal sources

including video DACs, CCD cameras, video switches or

75

Ω cables. The EL2006C provides a voltage gain of 2.5

while the potentiometer allows the overall gain to be

adjusted to drive the standard signal levels into the back

matched 75

Ω cables. Back matching prevents multiple

reflections in the event that the remote end of the cable is

not properly terminated. The 1k pull up resistors reduce

the differential gain error from 0.15% to less than 0.1%.
