... OVERVIEW The SM5301AS is a video buffer with built-in video signal bandwidth lowpass filter. The filter employs a 5- order Butterworth lowpass filter configuration. The filter characteristics have been optimized for minimal over- shoot and flat group delay, it has a variable cutoff frequency and guaranteed driver-stage channel gain differ- ence and phase difference values ...
