SM5304AV Datasheet Video Buffer

Manufacturer: Nippon Precision Circuits

Overview: SM5304AV Video Buffer with Built-in Analog LPF OVERVIEW The SM5304AV is a 75Ω 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.
