SM5309B 3-channel Video Buffer with Built-in wideband LPF OVERVIEW The SM5309B is a 3-channel video buffer with built-in 5th-order lowpass ﬁlters. The lowpass ﬁlter cutoff frequency range can adjust from 4MHz to 40MHz 1 by 256 steps. The lowpass ﬁlter supports 480i to 1080i format, video signal equipment analog input/outputs. For video input systems, the device functions as a next-stage ADC system anti-aliasing ﬁlter. For video output systems, the ﬁlter reduces video DAC aliasing and exter.
