ANALOG VIDEO EQUALIZING AND CLAMPING DISTRIBUTION AMPLIFIER

ANALOG VIDEO EQUALIZING AND CLAMPING DISTRIBUTION AMPLIFIER

The VCA6801N and VCA6802N are analog video distribution amplifiers with equalization and clamping. Both modules have unbalanced input and can compensate cable loss of up to 100m of Belden 8281 cable loss. The clamping can help the user reject DC offset and AC disturbance. The VCA6801N / VCA6802N can also provide +/-3db gain range adjustment. The VCA6801N has one input and eight outputs; and the VCA6802N has two inputs each with four outputs, or it can set to have eight outputs via jumper.
