SM5301AS 3-channel Video Buffer with Built-in Wideband Filters OVERVIEW The SM5301AS is a video buffer with built-in video signal bandwidth lowpass lter. The lter employs a 5order Butterworth lowpass lter conguration. The lter characteristics have been optimized for minimal overshoot and at group delay, it has a variable cutoff frequency and guaranteed driver-stage channel gain difference and phase difference values.
