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