Datasheet
OVERVIEW
The SM5304AV is a 75 Ω terminating resistance drive video buffer with built-in analog 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.
