... OVERVIEW The SM5306A is a 3-channel low-voltage video buffer IC that can drive a 75 Ω termination resistance load. The output buffer gain can be switched between 0dB and 6dB. A built-in sag compensation circuit enables a lower output coupling capacitance to be used. The device operates from a 3.0 to 5.5V supply. ...
