The SM5304A is a 75Ω terminating resistance drive video buffer with built-in 8th-order Butterworth lowpass filter. The filter cutoff frequency, controlled by the resistance connected to RFC pin, can be set to match any system resolution. The output buffer can be selected 0dB, 6dB, and 12dB. The feedback point occurs after the external coupling capacitors, and the coupling capacitances can be reduced.
