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.
