The SM5308A is a 3-channel video buffer with built-in 5th-order lowpass filters. The lowpass filter cutoff frequency range can adjust from 5.0MHz to 44MHz^*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 external noise and can drive up to two 75Ω terminating resistance. The cutoff frequency, signal input type, and output gain switching can be controlled using an I²C BUS^*2, and the I²C slave address can be set by ADS (3-state input) to allow up to three SM5308A on the same bus.
