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.
