SM5301BS

SM5301BS 3-channel Video Buffer with Built-in Wideband Filters with Filter Through Function OVERVIEW The SM5301BS is a video filter LSI with buffered outputs for VESA-standard ATSC digital TV. The filter employs a 5-order 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 output buffer-stage channel gain difference and phase difference values. It has also filter through mode.
