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 m
